when you look at thousands and thousands of charts a week, willy-nilly, you start to pay attention to some points. not to tell, what patterns. but you are trying to come up with some kind of decoding.
for example the situation: more or less flat within the day, suddenly a candle appears with a very small range – just some 3-5 Cents, but they pour volumes into 3-4 times higher than average, ie. it turns out such a wild spike against the background of even volume bars, and then sometimes this flat acquires a specific direction. not right away. and not sharp. maybe in minutes 30-60.. ie. the feeling that some big guy has dashingly entered, neatly, not to move the market, do not disturb the participants. and as if he already knows for sure, What will happen. Yes, sounds funny against the background of, that no one is destined to know, What will happen. however it looks like this. I want to watch and figure it out. and it seems in the trade-ideas demo you can configure such a filter. and the lag of 20 min does not play a special role.
