On those given example about I think the effective one is with the use of the MACD or the Bollinger bands it's hard to say by just putting the market indicators or the trend line its good if we have a guide such as these trading indicators on the example about on the fourth image you can make another buy order if the opposite happens on the trend this makes another indicator if the bullish trend.

I suggest use or put a real-time market graph so it's completely pleasing so most of us can understand thank you.
