Paste a YouTube link or describe the rules in your own words. We turn them into an exact specification, run them across futures history with real commissions and slippage, and simulate a prop firm evaluation from every possible start date. Then we tell you what happened — including when the answer is no.
You never send us a program. You send words, and we build the rules in front of you before anything runs.
A YouTube link, or plain language: entry, filter, stop, target, exit. Any of the 42 supported languages.
We show the exact specification we extracted, plus everything that was ambiguous and what we assumed. You correct it.
Minute bars, real commissions, real slippage. Entry on the next bar open, at the signal bar's close, or by a stop or limit order where the author places one. A market entry never exits on its own bar; an order is filled and its trade is managed minute by minute under the author's candle. Worst case when a bar is ambiguous.
We replay every firm's evaluation from every possible start date — trailing drawdown, daily loss, consistency rule — on every account each of them sells with a target we can measure, and report the share that passed. An account that allows fewer contracts than the strategy needs is reported as not reproducible, with the reason, rather than as a failure. The trading day is the market's session, 18:00–17:00 ET for CME, as the firms count it.
In the prop firm part of a check every position is closed before the firm's deadline. The swing trading part of the same check — your own account, no firm — holds positions through the daily close and the weekend, and is reported separately.
Extraction spends a membership extraction, not a check — a check is spent only when you press Run.
Sign in to run a check. Checks a month on the Basic plan: 2.
YouTube only. It is the one video site with automatic captions we can read, so it is the one we support honestly instead of pretending.
We read the video's captions — the author's words, nothing else. Anything shown on the chart without being said out loud we will not see. If you have watched it, add what the author does in your own words after the parse and we will check that too.
A level measured over a window of minutes — the high of the first 15 minutes, say — is computed only when the window divides evenly by the chart timeframe: 15 minutes works on a 5-minute chart, not on a 7-minute one. We refuse such a rule rather than compute it approximately, and the refusal comes at the run, when the check is already spent.
Every account they sell with a target we can measure is tested, on every platform — you do not have to guess which firm or which account to buy. An account that allows fewer contracts than the strategy needs comes back as not reproducible, with both numbers, rather than as a failure. Which target and drawdown your strategy actually clears is the answer, not the question, and it comes back in the report.
Optional letters are the ones about work that costs you nothing: we write when we start reading a strategy, when the rules are ready and when we could not read it. Letters about work you paid for — the verdict on a finished check — always come through. So do password reset letters: they are the only way back into an account.
We hold quote files for more symbols than this. This list is shorter, and deliberately so: it contains only the contracts for which we have verified tick size, dollar value and commission. Without those three numbers a backtest produces points, not money — and points are not an answer. The history shown is read from the files themselves, not typed by hand.
| Symbol | From | To | Years | Tick | $ / point | Commission |
|---|---|---|---|---|---|---|
| … | ||||||
Unused checks roll over, up to a cap. Cancel any time.
The limits your plan gives you when you subscribe are not reduced while the period you paid for is running. If they ever change for the worse, that takes effect only from your next renewal, and we tell you what changes before you are charged. Increases we can pass on to you sooner.
We re-verify each prop firm's rules at least once a quarter — usually monthly — and show the date of the last confirmed check next to that firm's name.
Swing trading is holding a position overnight and over weekends. Each firm on this list sets a time by which every position must be closed each day, so swing trading here means your own account and your own money — no firm.
We do not sell one bot to many people. You bring your own strategy, we build a bot on it for you, and you trade it as your own tool — the same thing you could have commissioned from any programmer. What you run is built for you, not a finished product bought off a shelf.
The two prices differ in what we may do afterwards, and neither touches your bot or your account. Private: we may not sell that bot on as ours. Discounted: we take a white label on the strategy and may build and sell a bot on it separately — elsewhere, not for your account and not instead of yours. Either way the bot we hand you stays yours.
The same strategy can reach us from more than one person. Strategies come from public videos, and a popular video has hundreds of thousands of viewers, so two of them sending us the same rules is the ordinary case and not a freak one. Private means the bot we built for you is never sold, transferred or offered to anybody — that holds without exception. It does not mean nobody else will ever have a bot like it: if somebody else brings the same strategy and takes the discounted price, we may build theirs and offer a bot on that strategy to others. It runs the other way too — if you took the discounted price, somebody else paying for privacy later does not take back the right you already granted us.
So look at where your strategy came from before you pay for privacy. Found it in a video? Then the private price buys you less than it sounds like it buys, and we would rather tell you that than take the money for it. Worked the rules out yourself, and they are nowhere public? Then a second person arriving at the same thing is rare, and privacy is worth what it costs. We charge where the money gives you something and not where it does not, and this is the most expensive thing we sell. Before a private order goes through we ask you to tick a box saying you have read this — not as paperwork, but so that nobody pays for privacy expecting something it does not give.
Discounted pricing grants us the right to trade the strategy and to offer a bot based on it to other customers. Private pricing does not. On both, we retain the right to trade it on our own account — stated here rather than hidden in a policy page. Every bot is delivered as is, for use at your own risk.
We went looking for every service that answers the same question and wrote down what each one does. The rows where someone else is ahead of us are here too, in a table of their own. Nothing here is about how well anyone trades — only about what the products do.
The middle column was read out of our own code, not out of our own marketing.
| What we compared | Karivox | The best of the others |
|---|---|---|
| The evaluation is replayed from every day the strategy traded | Yes How many of those days finish the evaluation — and, at a firm that sets no deadline of its own, how fast — is what sets the price of the bot. | We found no product that does this. The advice given elsewhere is to run ten start dates by hand and count. |
| Prop firm accounts covered by one check | Firms: — · Accounts: —. Every account they sell with a target we can measure, and every platform each firm runs. A strategy that trades one size throughout is measured in a single run; one that takes the position off in parts is backtested again at every size, because its money does not scale by multiplication. | Where a simulator exists at all, one preset is picked by hand, one at a time. |
| A warning about the firm's own rules on bots, beside every firm | Yes Beside every firm in your report stands a warning that its rules on automated trading are the firm's to change and yours to read — and we ask you to confirm you have read them yourself before a bot is ordered. | Not found. The others do not build bots, so the rule does not concern them. |
| Futures contracts we can price | Contracts on CME, CBOT, COMEX and NYMEX: —. Each with a tick size, a point value and a commission we have verified. Without those three a backtest produces points, not money. | Two on the nearest service: ES and NQ. Wider platforms cover more asset classes but do not simulate a prop firm evaluation. |
| Minute history | Years at most: —. Shorter on the newer contracts. The depth actually used is printed per market and never rounded up. | One, five or ten years by plan on the nearest service. TrendSpider holds far more but caps a single run at 2,000 to 30,000 candles. |
| A video link as the way in, for futures and prop firm rules | Yes We read the automatic captions, build the rules from them and show you the rules before anything runs. | faketrades.in takes a video link too, and it is free — but it trades Indian stocks, with no futures, no prop firms and no bot. |
| Languages the service speaks | Languages: — | English, on every service we found. |
| A working NinjaTrader bot at the end of it | Yes Written by hand, and only for a strategy that clears the bar. The more start dates it clears, the less the bot costs. | The nearest service says code export is on its roadmap and not available yet. Build Alpha and StrategyQuant X do export NinjaScript in one click — for $1,497 and $1,290 paid up front. |
The first three rows stood on this site as a promise until 5 September 2026. They were not true, so the promise was removed instead of being softened.
| What we compared | Karivox | Who has it |
|---|---|---|
| Walk-forward | Swing trading only Walk-forward guards against parameters fitted to the past. The rules themselves we never fit: they come from the author's own video and run exactly as he stated them, with no search over settings. In the Swing trading section one number is fitted — the risk per trade — and that number is checked out of sample: set on the first half of the history, applied to the second, and no bot step is given unless the second half holds. | QuantPeaks runs it on every backtest, five periods, by default. StrategyQuant X has it from its second tier up. |
| Monte Carlo | Swing trading only Monte Carlo reshuffles the order of the trades to ask whether the result rested on the order they arrived in. In the Prop firm section, replaying the evaluation from every day the strategy traded asks that on real data: each start date is its own sequence with its own drawdown, and the market dealt those, not us. In the Swing trading section there are no start dates to replay, so there we do reshuffle: the calendar months of the history are put in another order, and the report shows how deep the drawdown would have been. | QuantPeaks: 100, 1,000 or 5,000 runs depending on the plan. LuxAlgo gives 10,000 rule paths away for free. |
| A comparison against matched random entries | Swing trading only In the Swing trading section, yes: every strategy that made money there with enough data to judge is set against random entries on the same market, the same side and the same holding times, and no bot step is given unless it beats them. In the Prop firm section, no: there the bar is a real evaluation, trailing drawdown and all, from nearly every day the strategy traded — 90% of those days at the very least. | TrendSpider compares a rule set against a randomized control. |
| Tick data | No Minute bars, and we say plainly that they are not enough for targets under eight ticks. | QuantPeaks on its top plan, through Databento. |
| Length of the prop firm list | Firms: 5. More accounts than most, fewer firms than the longest list. | TradesViz holds 20 firms and more, 65 account profiles and more, for $29.99 a month — but it replays your own past trades, not a strategy you describe. |
| Paying for a year at a discount | No Monthly only. | QuantPeaks takes 17% off a yearly plan, TradeZella 25%. TrendSpider and TradesViz have one as well. |
| Anything outside CME futures | No Futures first. Forex and stocks come later, if at all. | TradeZella and TrendSpider cover stocks, forex and crypto. |
| A journal for the trades you actually place | No Not planned, either. | TradeZella and TradesViz are built around exactly that. |
| Source code exported in one click | No One bot is one piece of hand work, and only after the strategy clears the bar. | Build Alpha and StrategyQuant X export to NinjaTrader, MetaTrader and TradeStation among others. |

| Build Alpha | No trial at all | $1,497 once, for good |
| MyFXcoding | The advisor is free; the source code is not | Not published. MetaTrader and forex only. |
Free bots are a whole genre, and an old one. MyFXcoding writes MetaTrader advisors for nothing, forum coders have done the same for years, and most free bots in this market are paid for by a broker referral link. Anyone who has been around knows to look for that link first.
They ask you to show your own trading history and take your word for it. Forty of your own trades prove nothing, and that is the mistake this whole service exists to catch. We do the proving ourselves, on our data, against the rules of the firms we hold, from every day the strategy traded — before you have risked a dollar. When the answer is no, we say so, and there is no bot.
Everything said here about another service was read on that service's own pages. Where a page would not open for us, we left the line out rather than guess at it.
Everyone selling backtests omits this page. It is the reason to trust the rest.
It describes one path the market already took. The past is not required to repeat itself, and we do not promise that it will.
We built strategies with an edge of a known size put in by hand, and ran them through the same check. It finds the large ones and misses the small ones: the line falls around 0.55 of return per unit of drawdown. That is why we write «no edge could be detected» and never «this does not work». They are different things, and the second one we have no right to claim.
Inside one minute we cannot know whether the high or the low came first. We run both orderings. When they disagree, the report says inconclusive instead of picking the flattering one.
Prop firms change their rules without notice. We date every rule set we used and print the date in the report. Verify with the firm before paying an evaluation fee.
The checks and extractions your plan gives you each month renew on the day you signed up or last paid, not on the calendar's 1st for everyone. Checks or extractions bought separately never expire and are not touched by that renewal.
In the Swing trading section the risk per trade is chosen so that the worst drawdown on closed trades in the history stays within a fixed share of the account. That number is read off the past. Over another stretch of the same length a deeper drawdown is about as likely as not.
No, and we would rather you did not. We build rules from a bounded list of things a strategy can do, and we show you the result before anything runs. We never execute code you send us — running a stranger's program on our machine is a hole, not a feature.
Automatic captions. YouTube produces them for practically every video; other platforms do not. We support what we can actually read rather than advertising what we cannot.
Only what you have the right to share. Most marketplaces forbid both decompiling a product and handing it to a third party for analysis. Describe how it trades instead — that is what we test anyway.
You get the full report and the check is spent. A negative answer is the product. We would rather tell you before an evaluation fee does.
On the discounted tier, yes, and we may sell a bot based on it. On the private tier we will not offer your bot to anyone else, but we still keep the right to trade the strategy ourselves. And if somebody else brings us the same strategy — which on a public video is likely — what they choose is theirs to choose, and it does not touch your bot. Before a private order we ask you to tick a box saying you have read that. We say all this plainly because a promise we do not intend to keep is worse than an uncomfortable sentence.
The same rules measured as swing trading on your own account: your own money, no prop firm, no deadline for being flat, positions held overnight and over weekends. Every new check in which a stop has been chosen is measured this way as well, and the result is shown in its own section of the report. It describes the past; it does not tell you what an account will do next.
This answers questions about how Karivox works, what the plans include and what the documents say. It cannot advise on trading, evaluate your strategy or predict anything — and it will say so rather than guess.
Anything you bought and have not used is refunded here, immediately and without asking anyone. What you have already used is not refunded — the work was done and it cost us real money. A started month of a plan is not refunded either; cancel it and it stops at the end of the period you paid for.
All four documents, one after another. The button that accepts them is at the very bottom, after the last of them — there is no other way to tick the box, and you can close this window at any moment without accepting anything.
Pressing this records acceptance of these four documents as they are written above: the date, and a fingerprint of their exact wording. Closing this window instead records nothing.
We record which version you accept, and when. Accept and your membership continues exactly as it was. Deny and we stop the next charge — you keep working until the day it would have renewed, and you can accept at any time before then.
Type the address you signed up with. If we have it, a link to choose a new password is on its way.
A report is printed together with the strategy it was run on by default: numbers without the rules they came from can be read to mean anything.
