Liquidity and wycoff

Two trades I had taken on the pound dollar on thur-fri. In my opinion understanding what liquidity is and why it drives price is extremely important if u want to have any success. Understanding that if you don't enter on someone else's stop loss ; some one will enter on yours and that its a 0 sum game. Just remember when you enter a trade there is someone else entering the opposite trade at that exact price, think how that can be exploited
