Hi to everyone!
I want to write a Strategy wich uses the Supertrend Indicator from 2 different timeframes. My problem is that i am a beginner in mql4.
So it would be really nice if someone could write a simple example just for Buy when the 1MIN_Supertrend and the 5MIN_Supertrend is green(in an uptrend)!

I already searched for Supertrend EA´s but they are all full of risk/moneymanagement and a lot of stuff wich make´s it to much complicated for me to understand and learn!

So please could someone help me with a very basic ea who just open a position!?

Thank´s a lot in advance!

Here´s the Indicator to give the signal:

trend[i]=1;


if (Close[i]>up[i+1]) {
trend[i]=1;
if (trend[i+1] == -1) changeOfTrend = 1;
//Print("trend: "+trend[i]);

}

I believe I can save you some time here. I spent quite a long time with supertrend, it is a good indicator for manual trading. However, the problem when used in an EA is a problem common to nearly all indicators I have tried in EA's.

The problem is that the EA will work great whilst the market is trending up or down and make money.

But as soon as the market goes sideways or pauses waiting for direction, you get small zigzag movements which causes the EA to open and close buys way too late, the result is you get multiple small losses which cancel out the trend move wins and you end up going backwards.

I tried many filters to correct this, but to no avail.

thanks for your comment! I know that i doesn´t work when the market moves sideways. But I want to learn programming and for me this indicator is interesting.

please give me a simple example for coding this strategy!
