Chandelier Exit for MT4 - faithful port of everget's TradingView version with signal statistics - indicatore per MetaTrader 4

A line-by-line port of "Chandelier Exit", © 2019-present Alex Orekhov (everget), distributed under the GPL-3.0 license. The original is at tradingview.com/script/AqXxNS7j/. This port is released under the same license.

The logic is exactly the original's:

• ATR = multiplier × ta.atr(length) (Wilder RMA, seeded with an SMA).
• Long stop = highest(close or high, length) − ATR. It only moves up while the previous close stays above the previous stop.
• Short stop = lowest(close or low, length) + ATR. It moves symmetrically: only down while the previous close stays below the previous stop.
• Direction:
  • It turns long when the close breaks above the previous short stop.
  • It turns short when the close breaks below the previous long stop.
  • Otherwise it keeps the previous state.
• Buy / Sell when the direction flips, with a dot at the start of each new stop line.
• State highlight between OHLC/4 and the active stop. It is drawn as background rectangles so it stays behind candles and other indicators.

Inputs (original defaults): ATR Period 22, Multiplier 3.0, Use Close Price for Extremums on.

Added for MT4:

• Signal statistics panel. It buys at the bar after a Buy, sells after a Sell, and closes and reverses at the opposite signal. It shows:
  • trades, win rate, net points / pips / USD after spread + commission
  • profit factor, longest losing streak, max drawdown
  • the open trade and the cost per trade
• Daily session filter in your own time zone, with session shading and an optional close at session end. It is off by default (the panel counts the whole day); set Use_Session = true and your hours to use it.
• Trade marks with tooltips.
• Alerts on new signals.

Buffers for EAs ( iCustom ): 4 = Buy, 5 = Sell, 6 = long stop, 7 = short stop.

The panel describes past signals. It is not a backtest and not a promise of results.
