Renko chart EA with trend line (only for experts on renko)

This is Renko chart EA working with a trend line from an two color indicator (can use HMA in 20 periods for testing)

The EA is very simple, each time the trend line change the color, open a trade. When the color change a signal must appears, the trade must be opened as well as close the last trade if still open (when no TP set). The right place for the opening is after signal apear at the begining next renko bar.

I already have this EA however it doesn't work properly, the indicator (RTA6x buided for this) has mistakes at openings in live, it is a kind of bug or something related to renko, but the thing is  very often the opening trade happens at the end of the next bar after signal, or any other random place, instead at the begining as should be. This malfuntion makes the strategy do not work, so I need an expert on renko charts who has experience with renko and have the knowlegde to know what is possible or not with renko charts. I guess the problem is related to the indicator who has different behavior when placed on a chart and then when in live or with a backtest where place the signals one or two bars ahead it should do. I'm attaching two pictures shown the differences

The EA should have as parameters: Risk managemet (fixed volume, fixed amount, equity% and balance %), SL, TP, TS, trend period, and all the standar features to be able work with any asset or pair. 

I'm including the Renko builder indicator, RTA6x indicator,  and the EA in order be evaluate if need to be rebuilded.

Thanks in advance
