Very good. This mean you can download ninjatrader for free, get free data CQG and test all your ideas on backtest and than market replay or simtrading. You can stop to toss one envelope after another and explore conditions when your signals performing better or worse. You can save enormous amount of time using coding in ninja and also find new ideas. All this is free if you are good coder.
For example, you see that friday is worst Day for you and it seems to be correct from my experience. However you can find that first and only first trade statistically performing well. Just example. Another example. You do not believe that higher timeframe levels matters. Well, you can replace believe to know. You can explore subset of your trading signals that occuring near higher timeframe levels and i almost 100% guarantee that you will be surprised.
And so on. I recommend you research your trading signals deeper and coding in ninja is short way, much shorter that spend day by day in front of live market.
