A free, read-only utility. It reads an MT4 Strategy Tester report (.htm) and matches every backtest trade with your account history. It then shows the match rate, missed and extra trades, entry and exit slippage, delay, real commission and swap, and how much of the backtest edge survives live.
An MT4 port of QuantNomad's "UT Bot Alerts", one of the most-used scripts on TradingView. It draws the ATR trailing stop, Buy/Sell signals and bar colors, and adds a panel that counts what the signals would have done, after costs, inside your trading hours.
An MT4 port of the popular TradingView "Range Filter Buy and Sell 5min". The filter line only moves when price exceeds a smoothed average range, which filters out small swings. Includes Buy/Sell signals, target bands and bar colors, plus a signal statistics panel with a daily session filter.
An MT4 port of the classic Chandelier Exit as implemented by everget on TradingView (v6, 2025). It draws the long/short ATR stop from the highest or lowest close, Buy/Sell signals when the state flips, and a highlighted state fill, plus a signal statistics panel with a daily session filter.

Hi bros, yesterday I had an idea, pick all the best trend following default indicators on TradingView and made a super TS with the conjunction. Claude from Anthropic did the excellent job.
Exports closed trades to CSV with Maximum Adverse Excursion (MAE) and Maximum Favorable Excursion (MFE) in points and money, calculated from M1 history, plus the percentage of the available move each trade captured.
Opens charts for all Market Watch symbols or a custom symbol list in one click, on any timeframe, with an optional template applied to each chart. Skips charts that are already open and limits how many are opened at once.
Shades the chart background by volatility regime (Compression, Normal, Expansion) based on the percentile rank of the current ATR. Shows the current regime on the chart, alerts on regime changes and exposes buffers for Expert Advisors.

Draws Asian, London and New York session range boxes and marks liquidity sweeps: a closed bar that wicks beyond a completed session's high or low and closes back inside. Non-repainting arrows, extended session levels, alerts and iCustom-ready buffers.
Scalping Expert Advisor that reads a 3-period smoothed MA channel (High/Low), places pending stop orders either with the move (Trend) or behind it (Reversal), and trails the stop loss tick by tick. It includes broker-safe order handling for stop level, freeze level, retries and latency.(Inspired by Waygrow Ea)
A two-sided grid EA that lays a small symmetric ladder of pending stop orders around the current price, then escalates in two stages as fills accumulate: first a single opposite-side lot "bump," then a full martingale doubling sequence with two extra grid levels added. The whole basket is watched as one unit and closed the moment its combined floating profit reaches a target, after which a fresh grid re-arms automatically. Built with separate, auto-selected input profiles for XAUUSD and NAS100/US100, since the two symbols need very different lot sizes, grid spacing, and broker minimum-distance handling.
A complete, self-contained trend-reversal Expert Advisor for gold and silver. It waits for an averaged-bar colour flip to mark a possible reversal, then requires price to close back inside a volatility channel before committing to a trade. Stops are placed at real swing structure, position size is derived from your chosen risk, and the trade is closed early whenever the market prints an opposite-direction signal. No external indicators are required — all signal logic is built into the EA. Nothing repaints: every decision is made on closed bars only.
