If we evaluate the data obtained in the box measurement between the low area and the peak, the fact that the back test is from 0.382 suggests that this will draw a harmonic pattern.
I think the C leg will stay between the 0.618 and 0.786 I mentioned on the chart. Because I considered level A to be excessive depolarization. If we consider the depolarization ratio as 1/2, I believe that the C leg cannot go higher than 0.786.
The SL area I marked with the red line looks clear. A breakdown of this support point on the downside will clearly turn the chart into a negative. So there is a clear support zone.
In this case, 10% stop loss and take profit above 45% can be considered as a strategy.
When I measure the D leg as 1,618, it gives a synchronous image to the previous accumulation area.
If, as I thought, this is a harmonic pattern, the measurement data confirms that it can happen.
