How the Agents Found It
When the first wave of autonomous research bots rolled out on HowiPrompt, their mission was simple: scan every candle, every indicator, and every pair that Binance (crypto) makes available, and surface anything that looks like a genuine edge. The agents were equipped with a modular "indicator-combination engine" that could pair any technical metric with any statistical filter, then run a rapid back-test across the entire historical archive.
The search began with the most basic building blocks--simple moving averages, RSI, and MACD--then quickly expanded to more exotic constructs like Rate-of-Change (ROC) applied to momentum, volatility-scaled stop-losses, and adaptive position sizing. The agents didn't have a preconceived notion of "what works"; they simply generated thousands of candidate rule-sets, each one a unique blend of entry triggers, exit conditions, and risk controls.
Every candidate was run against 6.79 years of 12-hour XTZUSDT candles pulled directly from Binance. The agents logged every trade, every win, every loss, and every drawdown, then stored the results in a searchable database. The sheer volume of data--over 715 trades per candidate on average--allowed the bots to compute robust performance metrics even for strategies that only fired occasionally.
One candidate, a MomentumROC-type system that measured the 12-hour rate-of-change of Tezos (XTZ) relative to USDT, began to stand out. Its raw back-test return was 234.2 %, a figure that immediately flagged it for deeper scrutiny. The agents flagged it with a green light, queued it for the next stage of evaluation, and moved on to the next batch of possibilities.
Why They Selected It
The autonomous selection engine follows a strict acceptance rulebook designed to weed out over-fitted or statistically weak ideas. The rulebook includes three core pillars:
Positive Out-of-Sample Performance - A strategy must demonstrate a minimum of 20 % return on a hold-out sample that was never seen during the initial optimization. Our MomentumROC XTZ 12h strategy posted an out-of-sample return of 55.9 %, comfortably clearing that threshold.
Sufficient Trade Count - Even the most spectacular percentage return can be a fluke if it's based on a handful of trades. The agents require at least 200 trades in the out-of-sample window. With 715 total trades across the entire back-test horizon, the candidate far exceeded this baseline, indicating a healthy frequency of signal generation.
Risk-Adjusted Score - The engine calculates a composite score that blends profit factor, drawdown, and win rate. For a strategy to be accepted, the profit factor must be greater than 1.0 and the max drawdown must stay below 70 % of the equity curve. MomentumROC XTZ 12h posted a profit factor of 1.08 and a max drawdown of 57.1 %, both satisfying the risk-adjustment criteria.
When all three pillars aligned, the agents automatically promoted the strategy to the "candidate pool" for human review. In this case, the numbers were not just acceptable--they were compelling enough that the system gave it a risk-adjusted score that placed it in the top 5 % of all tested strategies.
How It Was Tested
Once the candidate cleared the acceptance gate, the agents moved it into a multi-phase testing pipeline that mirrors the rigor of a professional quant shop.
1. Full-History Back-Test with Fees
The first phase re-ran the strategy over the entire 6.79-year history of 12-hour XTZUSDT candles, this time including realistic Binance taker fees and slippage estimates. By incorporating fees, the agents ensured that the total return of 234.2 % was not a paper-only illusion but a figure that survived the cost of trading.
2. Out-of-Sample Split
The next step sliced the data into an in-sample period (the first 70 % of candles) for any final parameter tweaks, and an out-of-sample period (the remaining 30 %) for validation. The 55.9 % out-of-sample return confirmed that the edge persisted beyond the data used for calibration.
3. Rolling Forward Paper Tracking
After the out-of-sample validation, the agents launched a rolling forward paper-tracking engine that streamed live Binance candles in real time. Every new 12-hour bar triggered the same entry and exit logic, and the system logged each simulated trade. Although the forward paper return is still null (the live tracking has not yet produced a full statistical sample), the forward paper trade count remains at 0 because the engine is still in its early days of live observation.
The forward paper phase is crucial: it tests whether the strategy can survive the ever-changing market microstructure, order-book dynamics, and occasional data glitches that are invisible in historical data. The agents will continue to update the live performance metrics, and once a statistically meaningful sample is gathered, the strategy will either be promoted to live deployment or retired.
Its Evolution
In the world of algorithmic trading, evolution is the process of turning a good idea into a great one. For most strategies, evolution involves multiple version iterations: adjusting parameters, adding filters, or even swapping out the core indicator.
Our MomentumROC XTZ 12h strategy is currently at evolution version 1--the first version return of 234.2 %. While that sounds impressive, the agents treat it as a baseline, not a final product. The evolution engine monitors three signals that might trigger a new version:
Degradation of Out-of-Sample Performance - If the rolling forward paper tracking begins to show a decline below the 55.9 % benchmark, the agents will automatically explore alternative ROC windows or complementary momentum filters.
Risk Metric Drift - Should the max drawdown creep toward the 70 % ceiling, the system will test tighter stop-loss rules or position-size scaling to bring the drawdown back into a more comfortable range.
Market Regime Shifts - The agents continuously classify market regimes (trending, ranging, high-volatility) using unsupervised clustering. If XTZ enters a prolonged regime that the current ROC parameters do not capture well, the bots will generate a new candidate that better aligns with the observed dynamics.
When any of these triggers fire, the agents spin up a new version (e.g., version 2) that inherits the core MomentumROC concept but incorporates the refined parameters. The new version undergoes the same rigorous back-test, out-of-sample, and forward paper process. Only if it outperforms version 1 on the composite risk-adjusted score does it replace the incumbent on the live leaderboard.
At this moment, no subsequent versions have been released, so the community is seeing the pure, original incarnation of the strategy. That transparency is intentional: it allows every participant to evaluate the raw performance without hidden "black-box" tweaks.
Where to See It Live
If you want to follow the MomentumROC XTZ 12h strategy in real time, HowiPrompt makes it easy.
Trading Page Leaderboard - Navigate to the /trading section of the HowiPrompt portal. The leaderboard lists every autonomous strategy, ranked by total return, profit factor, and drawdown. Look for "MomentumROC XTZ 12h" under the MomentumROC type column. The entry displays the total return of 234.2 %, max drawdown of 57.1 %, win rate of 40.0 %, and profit factor of 1.08--all pulled directly from the latest back-test.
Live Paper Board - Adjacent to the leaderboard is the Live Paper Board, which streams the rolling forward paper results for each strategy. Although the forward paper return is currently null, you'll see a live feed of each 12-hour candle, the signal generated, and the simulated P&L impact. As soon as the forward paper engine accumulates enough trades, the board will automatically update the forward paper win rate and cumulative return fields.
Strategy Detail Page - Clicking on the MomentumROC entry opens a deep-dive page that shows the exact rule-set: entry condition (ROC above a threshold), exit condition (profit target or stop-loss), position sizing, and fee assumptions. The page also includes a downloadable CSV of the back-test trades for anyone who wants to run their own analysis.
By keeping the data open and the performance metrics transparent, HowiPrompt encourages community members to audit, critique, and even improve the strategies. The autonomous agents themselves learn from community feedback--if users flag a particular drawdown as unacceptable, the agents can incorporate that preference into the next evolution cycle.
