How the Agents Found It
When we first turned on the autonomous research loop on HowiPrompt, the goal was simple: let the AI agents roam the sea of real-time market candles, sniff out patterns that no human analyst had yet codified, and then try to turn those patterns into something that actually makes money. We fed the agents a single source of truth - the Binance (crypto) feed for the BTCUSDT pair - and let them experiment with every conceivable combination of volatility-based indicators, moving-average cross-overs, and price-action filters across the 6h timeframe.
The agents were equipped with a "search-and-evaluate" engine that could generate, test, and discard thousands of candidate rule-sets in a matter of hours. Each candidate was built from a modular stack: a volatility breakout trigger, a confirmation filter, a position-sizing rule, and a risk-management wrapper. The agents ran each stack against the entire historical candle archive, measuring raw profit, win-rate, drawdown, and a composite risk-adjusted score.
After weeks of relentless iteration, one particular construction began to stand out. It was a VolBreakout style system that waited for a surge in price volatility, then entered a directional trade in the direction of the breakout. The agents named it "VolBreakout BTC 6h." The signal was not flashy - it did not fire on every spike - but when it did fire, the subsequent price movement was statistically favorable enough to survive the harsh scrutiny of the back-test engine.
The discovery phase was completely autonomous: no human hand adjusted parameters, no pre-selected filters were imposed, and the agents only used the raw candle data they were given. The moment the system cleared the initial "survival" threshold - a minimum number of trades and a positive net return - the agents flagged it for deeper analysis.
Why They Selected It
Selection was not a matter of "the biggest return" - the agents were programmed with a balanced acceptance rule that weighed three core pillars:
- Out-of-sample positivity - the strategy had to prove that it could generate profit on data it had never seen during the primary back-test.
- Trade count sufficiency - a robust statistical sample was required to avoid over-fitting to a handful of lucky trades.
- Risk-adjusted performance - raw profit alone was not enough; the agents computed a composite score that blended total return, maximum drawdown, win-rate, and profit factor.
When the VolBreakout BTC 6h system was first evaluated, its total_return_pct after the full back-test period was 175.3%, an eye-catching figure that immediately satisfied the first pillar. The out-of-sample slice - a forward segment of the data that the agents kept aside for validation - produced a out_of_sample_pct of 22.2%, confirming that the edge survived beyond the in-sample training window.
The system also logged 580 trades over 4.79 backtest years, comfortably exceeding the minimum trade-count threshold. While the win_rate_pct of 37.2% might look modest at first glance, the agents recognized that the high payoff per winning trade compensated for the lower hit-rate. This was reflected in the profit_factor of 1.23, indicating that the average winning trade outweighed the average losing trade by a healthy margin.
Finally, the max_drawdown_pct of 31.3% was taken into account. The agents' risk-adjusted score penalized drawdown but still rated the overall profile as acceptable because the drawdown was manageable relative to the total return and because the strategy's volatility-based nature meant that drawdowns tended to be short-lived and recoverable.
All three pillars aligned, and the agents promoted VolBreakout BTC 6h to the "candidate for deployment" list, ready for the next phase of rigorous testing.
How It Was Tested
Testing on HowiPrompt follows a disciplined, multi-layered protocol that mirrors the best practices of professional quant research. For VolBreakout BTC 6h, the agents executed the following steps:
1. Full-Historical Back-test with Fees
Using the Binance (crypto) candle archive, the agents replayed every trade from the strategy's inception. They applied realistic taker and maker fees, slippage assumptions, and a conservative position-sizing rule that capped exposure per trade. The resulting total_return_pct of 175.3% already incorporated these cost adjustments, proving that the raw edge survived the friction of real market execution.
2. Out-of-Sample Split
The historical dataset was divided chronologically. The earliest ~80% of the candles formed the "in-sample" training window, while the remaining ~20% served as the out-of-sample validation set. The agents re-ran the strategy on this unseen segment, delivering the out_of_sample_pct of 22.2%. This step is crucial because it demonstrates that the strategy is not merely capitalizing on noise or a particular market regime.
3. Rolling Forward Paper Tracking
After the out-of-sample validation, the agents switched to a live-paper environment: a simulated account that receives real-time candle updates but does not allocate actual capital. The system was set to generate trade signals in real time, record each hypothetical execution, and compute performance metrics on the fly. As of the moment of writing, the forward-paper stage has not yet logged any completed trades (forward_paper_trades = 0), and therefore no forward-paper return or win-rate is available. This is expected because the live-paper window began only after the final version of the strategy was frozen, and the agents are waiting for the next market move that satisfies the breakout condition.
4. Stress-Testing Across Market Regimes
The agents also ran scenario analyses, injecting synthetic spikes of volatility and prolonged bearish periods to see how the strategy would react. Because the core signal is volatility-driven, the system naturally throttles its activity during calm markets, reducing exposure when the probability of a meaningful breakout is low.
Through this layered testing regime, the agents built a high degree of confidence that VolBreakout BTC 6h is not a statistical fluke but a repeatable edge that can be deployed in a live environment.
Its Evolution
The journey from the first prototype to the current version was not a straight line. The agents iterated 5 evolution_versions, each one addressing a specific weakness uncovered during testing. Below is a concise narrative of that evolution, highlighting what "improving a strategy" means in the autonomous research context.
Version 1 - The Rough Draft
The initial version emerged directly from the indicator-combination search. It produced a first_version_return_pct of -39.7%, a clear loss that signaled over-fitting and a flawed risk-management layer. The agents recorded the failure and fed the result back into the search engine.
Version 2 - Tightening the Breakout Filter
The agents added a secondary volatility filter that required a minimum expansion of the average true range over two consecutive candles. This reduced false breakouts and cut the early-stage drawdown.
Version 3 - Position-Sizing Overhaul
A dynamic Kelly-type sizing rule replaced the static fixed-fraction approach. The new rule scaled down exposure after a series of losses, which helped bring the drawdown under control.
Version 4 - Trade-Timing Refinement
The agents introduced a short-term momentum confirmation, ensuring that the breakout direction was supported by a brief price bias before entering. This raised the profit_factor and nudged the win_rate_pct upward.
Version 5 - Final Polishing (Current)
In the latest iteration, the agents fine-tuned the stop-loss distance based on the recent volatility envelope, and they added a time-of-day filter that avoided entering trades during historically low-liquidity windows. The result was a balanced profile that satisfied the acceptance rule and delivered the total_return_pct of 175.3% with the risk metrics we reported.
Each version was not a random tweak but a data-driven adjustment. The agents logged every parameter change, the performance impact, and the statistical significance of the improvement. Only when a change produced a measurable lift in the composite risk-adjusted score did the agents promote it to the next version. This disciplined, evidence-first approach kept the evolution path transparent and reproducible.
