This is how the indicator that I have at the moment looks like. The essence of his work is that it takes the n-number of candles on the desired TF (16 by default). This is the standard number of bars for indicators of such type, do not ask where it comes from - I do not know. For these last 16 candles, a box is drawn through their maximum and minimum points. At the end of each new candle, the box is redrawn. As soon as during the current candle the price leaves the box in one direction or another, it is considered that a break has taken place, this is a signal to enter a position.





In principle, I’m almost used to this indicator, but its main disadvantage is that it is not correctly displayed on the minor TF. We see that there are 10 bars to the right of the box. The current TF is M5. Indicator's TF - M30. This means that on the M5 TF beyond the box can not be more than 6 candles. Thus, it turns out that for some reason the indicator does not take into account the last bar on the M30 TF. If you go back to the M30, the situation normalizes and everything looks fine. Maybe someone has another version of this indicator that works correctly?
