Input Parameters

When loading the expert to any chart, you will be presented with a set of options as input parameters. Don't despair if you think they are too many, because parameters are grouped into self-explanatory blocks. Each functional parameter is explained below.

  • Trading Settings - Choose trading direction (regular, inverse, only long, only short) and if the EA should trade at bar closing only, or if it should instead execute every tick and trade before the bar closes.
  • Bollinger Bands - This parameter group holds the bollinger bands settings.
  • Trading Settings - You can enable or disable timeframes on which bollinger bands are evaluated as filters. For example, if you enable M1, M5, M15 and M30, trades will be taken when the price is overbought or oversold in all those timeframes simultaneously.
  • Session Settings - Enable or disable trading for the Asian, European or American sessions.
  • Position Management - This group of settings applies to trading decisions and trade management. You can select trading direction, break-even in pips, trailing-stop in %, trailing-step in pips, stop-loss in pip and take-profit in pips. Additionally, choose if trade should be closed when the price goes back to the bollinger bands average.
  • Money Management - In this settings block you can set the lotsize for the first trade, or allow the EA to calculate it by itself. It also implements a martingale behavior. Entering a manual lot size is recommended.
  • EA Settings - You can select the magic number for the trades, custom comment and manual pip value if you need to override the one the default one. Do not change these unless you know what you are doing.
