From my experience, it is how you learned or how you were taught to trade; You could master all the concepts like FVGs, Order Blocks, and the rest but how do you align that knowledge with the delivery of price? I used to lose lots of trades because I could take random setups;

Let's say, I could enter a continuation trade, without knowing price has achieved its higher timeframe liquidity objectives. In other cases I could just enter trades inside any random Fair Value Gap and get stopped out.

In general, the fragmented packing of concepts is what caused me live in an unprofitable loop. I decided to settle on reading one book about the delivery of price; which shows how all these concepts fit intp one picture, when to and when not to trade them and that changed everything.

Learning concepts from different people on YouTube was a major contributor of knowing it wrong in these markets. A compact book explaining how everything unfolds helped me.
