For open_trades, I would like to plot the min price (where trade will stop loss), and max price (where trade will take profit). I tried this, but:
1. Are TradeTrailLimit, TradeStopLimit the right parameters? I set Stop, Trail, TrailStep, and TrailSlope.
2. They are plot to a new chat, how can I plot them to the main price chart?

Code
for(open_trades) {
    	plot("Dotted",TradeTrailLimit,DOT,RED);
	plot("Dotted",TradeStopLimit,DOT,GREEN);
}
