Is there a way to get Donchian based HH & LL’s over n periods to persist and continue to draw their respective levels to the right rather than being re-written at the next period refresh? I appreciate this may make a chart look at little messy over the course of a day but for me it would be useful to identify S&R zones as the trading day evolves.
Since we never know in advance, how much time the higher high and the lower low will change in a day, it would involve to build multiple lines into a data array and there is not possibility to build array with ProBuilder.
So maybe, we could limit the number of past HH and LL lines that can be drawn on chart, and we could build something with, what do you think?
While the previous HH and LL’s get drawn, they eventually get overwritten every 60 bars…or whatever p is set to and so it begins to look like strange Darvas boxes. If it is possible to limit to the past 4 HH & LL’s that would be something 🙂
Maybe an alternative would be to only allow once the new HH and LL to be set with different periods. Then you can add many instance of the same indicator on the chart.
That would get me different overlaid Donchian channels if I understand your suggestion correctly. That isn’t what I am after. All I want to do is preserve an existing HHLL level to the right while re-writing the new one’s as they occur.
Recently I had an idea about drawing a kind of a “market profile” indicator overlaid on the recent candlesticks, made of recent highs/lows. It is still an idea, like many others on my to-do list.
