I prefer to wait for price action at red lines for shorting and similarly at green lines for long. I will wait for a strong price action to show me some at my levels and then only take a trade. We can see that has price has been following downtrend since Monday. I would like to follow that order till buyers feel that the price is cheap now.
Learning is when a Price action is formed see if some level is there or not, like important level that might have been missed.
