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.
Free multi-timeframe Supertrend indicator for MetaTrader 4 with clear trend lines and Buy/Sell signal arrows.
Visual MT4 indicator that draws the current or selected H1 range and nested M30, M15, M5 and M1 boxes. An EA based on this logic is in development.
