Hi everyone!
I'm in desperate need of help.

I need a system that works well during non-trending (ranging) market.

Do you know any?

small PS:
If you know such a system but there isn't an EA for it, I'll be willing to write one.

Just for information:

- Forex Market Conditions Forex Market Conditions, a graphic depiction

- evaluation of the market condition using six SMA indicators: Forex Trading With Simple Setup

- how to estimate and predict the market conditions (choppy, trend etc): the post with many links.

- market condition evaluation (incl choppy zones) and prediction using MTF_AbsoluteStrength_v1 indicator: original thread with indicators, live trading results and images; how to use indicator (rules): read all the pages starting from this page till this one.

Thanks! I'll be looking further into it.
Still, if anyone has an EA that works fine during ranging and choppy market, that would be nice.
IMHO: it should have a small profit target, very small drawdown, big stoploss and no trailing stop. It should not be a scalper. Something like trading daily.
I'll prefer to stay out of the market during flat and I can make good money on trending market.

I think you may look at threads about Ichimoku indicator. This indicator is very good for H4 and D1.

Is this indicator or EA ?

It is an indicator, a good indicator to measure market condition. Look at thread start by New Digital how ichimoku works, Or else you can visit ichiwiki by kumotrader.
