Writes a CSV journal of every trade with the exit reason, and a report that shows how far each trade ran, in R. It never trades.

A one-file library that handles how an EA trades: pre-trade checks, normalisation to broker limits, safe retries, one order per signal, isolation by magic number and state recovery after a restart. Lot by risk, daily loss limit and equity floor included. Verified in the Strategy Tester.

A regime-classification oscillator that measures how far, and how persistently, price deviates from a rolling volume-weighted VWAP in standard-deviation units, separating trending conditions from ranging ones.

Close all positions panel for MT5: seven buttons to close all, buys, sells, winners, losers, the chart symbol or delete pending orders, on Gold (XAUUSD), forex or any symbol, for manual trades and any EA. Open source code.

Draws the high and low of a chosen time window and alerts on the first break on each side. The levels are also available through iCustom.

Exports your closed trade history to a CSV file with one row per position (not per deal), ready for Excel, Python or any journal. Each row has ticket, symbol, magic number, comment, side, volume, entry and exit time and price, duration, initial SL and TP when known, gross profit, commission, swap, net result and R multiple. It also calculates MFE and MAE (best and worst price reached while the trade was open, in points and in money) from the M1 bars between entry and exit, plus the entry session (Asia, London, New York) and weekday. Filter by magic number (lists and ranges) and symbol (wildcards), pick the period, the column separator (; or ,) and the decimal mark, and save to MQL5\Files or the common folder. Tested on hedging accounts and in the Strategy Tester (netting logic included; feedback welcome), where the file is written when the test ends. Read-only: it never opens, modifies or closes a trade. No DLLs, no web requests.
