How do I register levels in the Expert Advisor?

khorosh:
Do you determine the trade by the horizontal position of the standard deviation channel and the width of the channel? And how many bars do you take and on what TF?

I do not even define the channel, but the value of the standard deviation for the nth number of bars. So far only so, on 15 minutes now I look, I took for 10 bars, there are a couple of deals here, I try to adjust to them and see what will happen in the end.

You can define levels in different ways. By the maximum accumulation at the price level of Close, Low, High, fractals. By the maximum number of crossings of the price level. By the minimum number of price level crossings. All these options are implemented in the form of a script. There are also round levels. For round levels, there are many indicators in the public domain.

On forts, round levels do not work much, for the maximum accumulation of prices, this is too random, prices can draw a lot of excess. I have already drawn fractals, but there are millions of them and how to draw fractals too. Now I’m trying to come up with something with the fact that at the time of trading, as a level, use the standard deviation, if it falls below a certain value, we wait for the value to increase and look where.. As an option.. but still not the same. I’m trying to prescribe pyramiding in a global sense, but it should not be stupid grid, but according to some logic. Rollback moments are too universal until I found a way. As a result, at least from the standard deviation until I start. Entrance on the standard indicator
