Intermittent results between Indicator and Bot

Hello -

I am trying to learn how something works here, and I am finding things to be intermittent.
I have coded a stupid simple indicator - this indicator plots a marker over every bar that satisfies the criteria. I can visually see it is funtioning properly.

I then coded this exact same simple sample pattern into a bot, making sure to refactor the syntax apporpriate for bots vs. indicators.

I then backtest the pattern.  Using Deal Map under viewing options, I can visually see that the bot is funtioning properly. But not all patterns marked by the indicator, are recognized by the bot. Many, evem most, are marked but tnot all...

This seems evident (but not consistent) with other tests I have made. 
Have you any thoughts please?
