# Researching and Analyzing Trading Algorithms Using AI

> Adapt file names, symbols, periods, risk limits, and requirements to your project or preferences. Preserve an unchanged baseline and test the algorithm in a demo environment before live use.

Existing algorithm and codebase study:

Inspect this algorithm and at most eight directly referenced files. List any remaining dependencies without analyzing them. Explain signal, sizing, execution, state, and data paths. Identify hidden assumptions, duplication, unused inputs, and extension points. Cite every finding by file and function, and do not modify code.

Live-market-data-driven assumption check:

For one requested asset, resolve the broker symbol and inspect current properties, spread, the latest 100 H1 bars, and up to 20 recent news or fundamental items. Check the strategy volatility, session, mean-reversion, and stop assumptions, record retrieval times, separate facts from inference, and suggest research ranges without changing the strategy.

Conformal uncertainty research:

Test conformal uncertainty on EURUSD, GBPUSD, and XAUUSD using 240 H1 bars per-symbol. 120 for fitting, 60 for calibration, and 60 untouched. Compare abstention and interval width sizing with fixed and volatility sizing, including spread and commission, and report interval coverage and net results by symbol.

Online change-point study:

On the latest 300 EURUSD H1 bars, compare a constant-hazard Bayesian change-point filter with no filter. Evaluate only three responses, pause, half risk, or switch to mean-reversion, and report detection delay, false alarms, foregone profit, drawdown, and net performance on the final 75 bars.

Order-flow entropy study:

Using the latest 3,000 EURUSD ticks, test whether entropy of signed changes, inter-arrival time, and volume states predicts next 100-tick move magnitude. Compare the real signal with 20 block-shuffled controls, then combine it once with completed M5 momentum to test direction after spread and commission.

Cross-asset lead-lag discovery:

Using EURUSD, GBPUSD, and USDJPY and their latest 300 H1 bars, test one and two-bar lead-lag links across three 100-bar windows. Retain only links stable in all windows, compare them with common-factor and own-symbol momentum baselines, and simulate the strongest laggard trade on the final 60 bars.

Event-conditioned market response:

For one symbol, align up to 20 latest unique news items that already have four hours of post-publication data with M5 and H1 data from two hours before to four hours after publication. Do not wait for incomplete windows. Compare drift, reversal, volatility, and spread normalization with the same number of matched non-event windows, using delayed entries and conservative costs.

Complexity-based market anomaly study:

For EURUSD and GBPUSD, calculate approximate entropy, tail behavior, volume-to-tick-count divergence, autocorrelation, and detrended cross correlation from the latest 5,000 ticks each. Flag unusual market-quality regimes and describe them without inferring manipulation.

Strategy reality-gap analysis:

Compare the assumptions of this EA with the latest 50 account fills, 2,000 symbol ticks, and current contract settings. Replay one month with measured costs and three harsher levels, 25 percent, 50 percent, and 100 percent above observed degradation, and report the break-even slippage, delay, and spread.

Double out-of-sample walk-forward study:

Evaluate one H1 strategy on one symbol over six months. Compare only two walk-forward schedules, with at most four folds and two fixed parameter sets per schedule on the first four months. Freeze the better schedule, and use months five and six once as sealed tests. Include the original fixed-parameter baseline, costs, and failed schedule.

Codebase explanation:

Read MeanReversion.mq5 and at most eight directly referenced includes. List any remaining includes without analyzing them. Produce a call graph and concise specification of signals, exits, sizing, execution, state, dependencies, unused inputs, and every current-bar read.

Hypothesis before implementation:

Turn this idea into a falsifiable plan for one symbol and timeframe. Define one primary hypothesis, one baseline, costs, a chronological train-validation-test split, three evaluation metrics, rejection criteria, and the researcher choices most likely to cause selection bias. [Paste idea]

Walk-forward evaluation:

Create a three-fold walk-forward test for this EA, with four weeks of training and one week of testing per fold. Compare anchored and rolling training, evaluate no more than two parameter sets per fold, include trading costs and delay, and aggregate only out-of-sample trades.

Parameter stability:

Evaluate two key inputs on a 3 by 3 grid around their current values using one three month H1 test. Report trade count and performance for all nine combinations, highlight broad acceptable neighborhoods, and reject isolated peaks.

Multiple-testing audit:

Using one completed optimization results file, count all trials and compare the winner with 100 bootstrap selections under a no-skill benchmark. Report the raw and selection-adjusted Sharpe measures, trial dependence assumptions, and any missing information.

Ablation study:

Create four one-month tests of this EA. Baseline, signal removed, filter removed, and custom exit replaced by a fixed exit. Keep risk controls unchanged and compare out-of-sample trades, drawdown, turnover, and complexity.

Cross-market robustness:

Test the fixed strategy on EURUSD, GBPUSD, and USDJPY over the same one-month H1 period. Normalize price and risk correctly, include failures, and state whether performance is shared or driven by one symbol.

Successive-halving optimization:

For MeanReversion.ex5 on EURUSD M15, use a completed historical window of 10 trading days and prepare 12 combinations of Lookback, EntryZ, and ExitZ. On the first five days, run all combinations using M1 OHLC, then rerun four candidates with at least five trades and drawdown below 5 percent over the same days using every tick. Test two finalists on the following five days. Preserve each stage's configuration, report, and journal.

Full-search versus genetic-search experiment:

Optimize RangeBreakout.ex5 on EURUSD M15 over five days using Open prices and 81 combinations: LookbackBars=10..30/10, StopATR=1..3/1, TargetR=1..3/1, and EntryMode=0..2/1. Run full and genetic searches with identical settings, compare visited passes, failures, and leading regions, then validate each winner on the following trading day.

Optimization-criterion disagreement study:

Run the same 27-pass EURUSD H1 optimization of GoldTrend.ex5 for five days using maximum Sharpe, minimum drawdown, and maximum recovery factor. Keep all other settings identical. Deduplicate the leading parameter set from each run, backtest at most three candidates on the following two days, and report which remain strong across criteria.

Optimization failure cartography:

Run a 27-pass optimization of RangeBreakout.ex5 on EURUSD M15 over five trading days using Open prices. From the report and journal, classify failed passes as invalid inputs, initialization, history, no trades, resource, numeric, or unknown. Correct only objectively invalid ranges or validation, rerun once, and report how many additional passes became valid.

Behavioral-equivalence compression:

Take the six highest-ranked passes from the latest EURUSD M15 optimization and rerun each over the same five days. Compare trade times, directions, volumes, exits, and results; group behaviorally identical parameter sets; and identify inactive or compensating inputs. Create a reduced SET file and confirm one representative from each group in one final run.
