How Our Autonomous Agents Stumbled onto a Hidden Gem
When the HowiPrompt research engine first went live, the goal was simple: let a swarm of self-directed AI agents roam the historical price landscape, mix and match technical ideas, and surface anything that looked truly profitable. The agents were not given any pre-selected symbols or indicator recipes. Instead, they were handed a raw feed of Binance crypto candles (the same data you would see on any charting platform) and a set of "exploration rules" that encouraged curiosity, diversity, and disciplined evaluation.
The agents began by pulling apart every weekly candle for the SOL/USDT pair--over 5.96 years of data, which translates to roughly 300 weekly bars. For each bar they computed dozens of standard technical components: moving averages, RSI, Bollinger Bands, and, crucially for this story, the MACD (Moving Average Convergence Divergence). The agents then entered a combinatorial search phase, where they tried every plausible way to blend MACD signals with momentum filters, stop-loss thresholds, and position-sizing formulas.
What set this search apart from a typical grid-search run in a research notebook was autonomy. The agents could rewrite their own code, spin up new hypothesis tests, and even create tiny "sub-agents" that specialized in a particular slice of the data (for example, only the high-volatility weeks). They logged every experiment in a central ledger, tagging each candidate strategy with a compact fingerprint of its parameters and performance metrics.
After thousands of permutations, a handful of candidates rose above the noise. One of them, which the agents christened "MacdMomentum SOL 1w", displayed an eye-catching combination of high return, decent win-rate, and a risk profile that survived the agents' internal sanity checks. The agents flagged it for deeper scrutiny, and the story of how it moved from a curiosity to a live-paper contender began.
Why the Agents Chose This Strategy
The autonomous selection process was governed by a set of acceptance rules that the agents applied uniformly to every candidate. The rules were deliberately strict, because we wanted to avoid the classic "over-fit to the past" trap that haunts many retail backtests.
Positive Out-of-Sample Performance - The agents split the historical data into an in-sample training window (the first 80 % of the timeline) and an out-of-sample validation window (the final 20 %). A candidate had to generate a positive return on the out-of-sample slice. MacdMomentum SOL 1w posted an out-of-sample return of 80.2 %, comfortably clearing this hurdle.
Sufficient Trade Count - A strategy that trades only a handful of times can look spectacular in a backtest but is statistically fragile. The agents required at least 30 trades across the full backtest period. MacdMomentum SOL 1w executed 50 trades, providing a solid sample size for evaluating win-rate and profit factor.
Risk-Adjusted Score - The agents calculated a composite score that blended three elements: total return, maximum drawdown, and profit factor. The score rewarded high returns while penalizing deep drawdowns. MacdMomentum SOL 1w delivered a total return of 638.4 %, a maximum drawdown of 43.8 %, and a profit factor of 2.21. When weighted together, the strategy's score placed it in the top 2 % of all tested ideas.
Win-Rate Threshold - A win-rate below 50 % often signals a reliance on a few massive winners, which can be dangerous in live markets. The agents set a floor of 60 %. MacdMomentum SOL 1w achieved a win-rate of 62.0 %, confirming that the edge was spread across many trades rather than concentrated in a few outliers.
Data Integrity - All calculations had to be performed on Binance (crypto) data, with realistic fee assumptions baked into the backtest. This ensured that the numbers we were looking at reflected the friction that any real trader would face.
Only after passing each of these filters did a candidate earn the badge of "approved." MacdMomentum SOL 1w was the sole survivor of that rigorous gauntlet, and the agents automatically promoted it to the next phase: forward-looking testing.
How the Strategy Was Put Through Its Paces
Multi-Year Backtest with Realistic Fees
The agents reran the strategy over the entire 5.96-year horizon, this time applying a 0.075 % taker fee (the standard Binance rate for the SOL/USDT pair). The fee was deducted on every entry and exit, ensuring that the 638.4 % total return figure already accounted for transaction costs. The backtest also incorporated slippage assumptions based on average weekly volume, a detail that prevented the agents from inflating returns through unrealistically tight fills.
Out-of-Sample Split
To guard against curve-fitting, the agents kept the out-of-sample period separate from any parameter tuning. The 80.2 % out-of-sample return was generated without any further adjustments to the MACD parameters or the momentum filter. This demonstrated that the core logic of the strategy--using the MACD histogram to signal trend direction, then confirming momentum with a short-term price acceleration filter--was robust across different market regimes (bull, bear, and sideways periods).
Rolling Forward-Paper Tracking
Once the backtest cleared, the agents launched a live paper-trading instance. In this mode, the algorithm receives the latest weekly candle as soon as it closes, computes the entry/exit signals, and logs a virtual trade. The paper engine mirrors the exact same position sizing, stop-loss, and fee model used in the backtest.
Because the strategy operates on a weekly timeframe, the paper engine updates only once per week, giving the agents ample time to verify each signal against the fresh market data. As of the moment of writing, the forward-paper run has 0 trades logged (the next weekly candle is still forming), and consequently null values for forward-paper return and win-rate. This is expected for a weekly system; the first live paper trade will be recorded after the next candle closes.
The agents continue to monitor the live paper performance in real time, automatically flagging any deviation from the expected risk-return profile. If the drawdown begins to exceed the historical maximum or the win-rate drops significantly, a self-diagnostic routine will trigger a re-evaluation, potentially prompting a new version of the strategy.
The Evolution of "MacdMomentum SOL 1w"
In the HowiPrompt ecosystem, evolution means incremental improvement while preserving the core edge. The agents treat each approved strategy as a living organism: they periodically run "mutation" cycles that adjust parameters, replace sub-components, or experiment with alternative filters.
For MacdMomentum SOL 1w, the evolution_versions count stands at 1. That means the current incarnation is the first version that passed all acceptance criteria. The agents have already logged a series of pre-version experiments--different MACD fast/slow periods, alternative momentum thresholds, and varied stop-loss distances. None of those variants beat the baseline on the composite risk-adjusted score, so the agents chose to lock in the original configuration.
Future evolution could take several forms:
Parameter Fine-Tuning - Slightly nudging the MACD fast line from 12 to 13 periods, or adjusting the momentum filter's look-back window, to see if the win-rate can be nudged higher without sacrificing profit factor.
Hybridization - Adding a secondary filter, such as a volume-weighted average price (VWAP) condition, to filter out low-liquidity weeks that tend to produce larger slippage.
Risk-Management Enhancements - Introducing a dynamic position-size algorithm that scales exposure based on recent volatility, aiming to reduce the 43.8 % maximum drawdown.
Each mutation is automatically backtested and evaluated against the same acceptance rules. Only if a mutation outperforms the incumbent on the composite score does the agents promote it to a new version. Until such a breakthrough occurs, MacdMomentum SOL 1w remains at version 1, and the agents continue to monitor its live paper performance with the same diligence they applied during the original discovery phase.
