How to find high probability areas?

Hi guys,

In my little time in Forex, I have been studying and researching. I read that the best of the best would be to join on board with high probability areas, where banks and institutions enter to buy or sell.

They say that the market always shows traces that the big banks when they open their operations.

Do any of you know areas or traces that banks inevitably leave?

Sorry for my ingles
The most profitable trading strategy is to trade in the direction of the trend, define your risk before taking the trade, and stay in it as long as possible.
Demo is the best trading practice resources in my opinion. A new traders should stick to it for more than six months or more before moving to real accounts.
