The indicator was created specifically for the Eurodollar M30 timeframe.
In fact, it contains a trend - a red zone above which the price usually rises, below it falls.
This is an indicator that does not redraw, when the price crosses the zone, it either remains in place or moves below. Signals rarely occur on the M30 and therefore the reliability is more than enough.
However, there are additional Yellow and Green lines. These are longer trends, so within them a trend in the immediate direction is recognized.
With the acceleration of the market, you can earn enough, however, it is also good in the flat.
It is better not to touch the parameters with your hands simply because there are actually a lot of them.
