Bot only triggers initial trade // Trail does not trigger

I am coding a (relatively) simple bot.

Use on Renko Charts

Open trader after two bars close same color

Trail Stop

Stop should close trade just as another is opened in opposite direction (i.e. long gets closed just as short criteria is met)

Trail stop does not trigger, and the bot only opens the initial position, and no others.

Please help me correct these two issues, thanks!
