If we had to simplify trading we would only talk about price structure. It's the key. Having proper price structure such as Supply/Demand dramatically increases the probability of success.
Watch in this live /NQ Futures trade how we knew exactly where to look for our sell triggers. Price over the past 4 trading days has built picture perfect range and when you let price do this you can exploit the heck out of it.
If you can't see or don't know if you have proper price structure to the left....then it's likely not a good trade.
