I have had past success using ADX to identify non-trending markets (ADX < 20). In non-trending markets, market neutral strategies, such as selling straddles and selling iron condors, generally perform well. But I have had mixed results when using ADX to identify breakouts / trending markets. (ADX > 20).
put the adx on 1 min chart add 20 day ema ...when you get larger range bars blowing through the ems and the adx is 30 or more trade the pull back to the ema.. that is the only system i have seen that works
