Scalping strategy in London killzone

This strategy is based on taking liquidity from the PDL and PDH (Previous Day High & Low). It can also be used with PWH and PWL (Previous Week High & Low). The objective of the strategy is to look for a short position when the price reaches the previous day's high, or to look for a long position when the price reaches the previous day's low. Profit taking will be the opposite place, ie if we take a short position, we will take profit at the previous day's low and vice versa.
