确定关键水平的价格行动 (Price action to determine key levels)

I have created my own analysis technique for identify key supports (S/R) on whatever charts.
I would like to share you the results in order to help some people in their trading.

The basis of the strategy is simple. It is based on Price action and high and low on 3 TF:

M15 short trend
H4 trend
D1 Big trend

The strategy is to take a trade on M15 with a very tigh SL in the trend of H4 and D1.

I will post 3 graphs asap
