Not sure how you used the DMI, I see the MACD works pretty good but I was using Unirenko... what bars are you using...you say it didnt work over 100 days, are you using a strategy... I have a couple of indicators for the NQ...one of them is SMAHist...when I break over the 3 or under -3 i see a potential trade....otherwise you are just looking at chop...are you using NT7 or NT8.....if NT7 there is an Dynamic SRColor Bands(page 18 of indicators NinjaTrader 6.5) that show Support and Resistance set it at 3 rather than 21 (its a 9 in the example)....all of these indicators are available in Futures.io also another you may find interesting ...
