Combine two indicators into fully automatic EA

Here is the strategy:

To filter signals from one indicator (ADX_Crossing_v.2.0.MX1Alert.mq4) with signals from another one (! Symphonie Extreme Indicator v3 600__2)

The algorythm is very simple. A minor or major Top detected by Symphonie Extreme Indicator in the range of 3 bars before the ADX signal works as a proof,a validation of ADX sell signal.

A minor or major Bottom detected by Symphonie Extreme Indicator in the range of 3 bars before the ADX signal works as a proof,a validation of ADX buy signal.

It seems to work well with US100 index.

The  properties of an EA:

-trailing stop
