Impulse Catcher

The Impulse Catcher Expert Advisor is based on the Impulse Checker indicator. The main operation principle lies in utilization of strong directional price movements. The EA opens positions the moment a strong directional price movement appears. The EA does no use hedging, martingale, grid and other risky strategies.

The EA uses only tick data in its calculations, so changing the timeframe does not affect the entry and exit points. Use the timeframe, where you can easily monitor trading on the account. With the properly selected parameters and sufficient market volatility the EA is able to work on any instrument.

Description of Yurchenko's trailing

This unique type of trailing stop ignores the changes in price. This trailing stop modifies SL every N minutes by N points. All opened deals have the same algorithm for moving SL, corrected by the current volatility and the size of the initial impulse.

Input parameters

Basic Settings:

Magic - identification number of trades.
Deposit - if set to 0, the volume is calculated based on the account balance.
RiskonPosition - risk per deal in percents.
VolumeonPosition - volume of each position in lots.
MaxPositionsNumber - the maximum number of simultaneously opened trades.
CloseIfOpositeSignal - close all open positions when an opposite signal appears.
TrailingByYurchenko - enable/disable Yurchenko's trailing.
