Somewhere I read not to over optimize a strategy. What do you suggest? >N times?

When I load and scan bars, I get MQ 50.0. What does that mean or is it something to worry about?

What are the yellow lines on the graph that you can barely see?

Awesome software. It must be a labor of love because there is a ton of work you have done.

if (indicator[t-1] < low[t-1] and indicator[t] > high[t]) entry[t] = open[t];

In that case the previous bar was above the previous indicator value and the current bar is below the indicator. (The price jumps below the indicator.) The price doesn't touch the indicator but we don't want to miss the entry so we make the entry equal to the bar opening price.

The problem in real trade is that we don't know the bar's high / low prices before its end. That's why we corrected the formula to:

if (indicator[t-1] < low[t-1] and indicator[t] > open[t]) entry[t] = open[t];
