Educational guides for algorithmic forex traders, from the makers of the no-code EA Builder for MetaTrader 5.https://aistrategyminer.comhttps://aistrategyminer.com/en/guides/backtesting/backtest-reportshttps://aistrategyminer.com/en/guides/backtesting/backtest-reportsAn MT5 backtest report is a claim about one set of trades on one price history, and both halves move the numbers. We read 23 MT5 reports against their trade ledgers: in 14 of 20 the headline flatters the period the settings were chosen on, one covers only 303 of its own 315 trades, and one EA re-run on another data source went from 1.35 and a pass to 1.13 and a fail.Wed, 26 Aug 2026 00:00:00 GMTGuidebacktestinghttps://aistrategyminer.com/en/guides/builder/create-an-eahttps://aistrategyminer.com/en/guides/builder/create-an-eaAssemble an Expert Advisor from blocks in a browser, compile it to a real .ex5, and test it before it ever sees money. Includes the number nobody quotes: what the 87 shipped starter templates score at their stock settings, measured from the Builder's own records.Tue, 25 Aug 2026 00:00:00 GMTGuidebuilderhttps://aistrategyminer.com/en/guides/builder/macd-eahttps://aistrategyminer.com/en/guides/builder/macd-eaWire a MACD crossover Expert Advisor from blocks in a browser, compile it to a real .ex5, and read its numbers honestly. Includes the result that should worry you most: the Builder's own parameter search found a MACD setting that scored 1.14 out of sample, then collapsed to 0.74 on the window before it.Tue, 25 Aug 2026 00:00:00 GMTGuidebuilderhttps://aistrategyminer.com/en/guides/backtesting/parameter-optimisationhttps://aistrategyminer.com/en/guides/backtesting/parameter-optimisationWe ran parameter searches on eight of our own strategy templates and adopted none of them. The useful part is how each one failed: the biggest in-sample winner fell the furthest, one design passed a single out-of-sample check and still collapsed, and two never beat 1.0 even on the period they were fitted to. Here is the procedure, and the reading that stops you shipping the top row.Tue, 25 Aug 2026 00:00:00 GMTGuidebacktestinghttps://aistrategyminer.com/en/guides/ea/risk-managementhttps://aistrategyminer.com/en/guides/ea/risk-managementRisk management for an EA starts before you attach it. 23 EA backtest records, all run on the same 10,000 deposit, had worst drawdowns from 0.67% to 26.5% of it — one deposit cannot fit that spread. Here is how to size from the record, and the four numbers that decide when you switch an EA off.Tue, 25 Aug 2026 00:00:00 GMTGuideeahttps://aistrategyminer.com/en/guides/builder/rsi-eahttps://aistrategyminer.com/en/guides/builder/rsi-eaWire an RSI reversal Expert Advisor from blocks in a browser, compile it to a real .ex5, and read its numbers before it sees money. Includes the figure nobody publishes: the Builder's own RSI template scores a profit factor of 0.94, and its recorded parameter search never found a winning setting — not even on the period it was fitted to.Tue, 25 Aug 2026 00:00:00 GMTGuidebuilderhttps://aistrategyminer.com/en/guides/backtesting/run-a-backtesthttps://aistrategyminer.com/en/guides/backtesting/run-a-backtestOpen the Strategy Tester, pick the data and settings that decide the answer, press Start, and read the report without fooling yourself. Includes one run quoted end to end, and the number nobody checks: across 23 finished runs the equity drawdown was deeper than the balance drawdown every single time.Tue, 25 Aug 2026 00:00:00 GMTGuidebacktestinghttps://aistrategyminer.com/en/guides/ea/use-a-free-eahttps://aistrategyminer.com/en/guides/ea/use-a-free-eaA free EA is worth running only after it passes four checks. Design your own on the free Builder canvas to compare: of the 53 measured free templates, one meets the thresholds the Builder uses to pass a design. Here are the checks for any free EA, the MT5 setup, and the numbers that mean stop.Tue, 25 Aug 2026 00:00:00 GMTGuideeahttps://aistrategyminer.com/en/guides/ea/ea-profitabilityhttps://aistrategyminer.com/en/guides/ea/ea-profitabilityMost are not, as they come. We ran 53 standard EA designs through one identical MT5 test: 11 ended at or above a profit factor of 1, and one met a real pass bar. Here is what separates the few that earn from the many that almost do, why a profitable year proves little, and how to check an EA before it trades.Fri, 14 Aug 2026 00:00:00 GMTGuideeahttps://aistrategyminer.com/en/guides/ea/ea-vs-manualhttps://aistrategyminer.com/en/guides/ea/ea-vs-manualEA vs manual trading usually turns into an argument about judgement. Replaying 14 EA backtest records under the stop rules a human would actually use gives a sharper answer: switching off after three losses in a row would have given up 93% of what the same rules produced when left alone.Fri, 14 Aug 2026 00:00:00 GMTGuideea
