I'm quite new with Motivewave and I have a question regarding the history of the order heatmap:

I open Motivewave mostly pre market, so the heat map can be build up. My Chart is set to 1 second. For the Orderheat Map "max history" I just calculated how many hours I need and convert it to seconds.
At certain times I noticed, that a lot of the history is flushed... that is the white background on the screenshot... I expect this not to happen according to my max. history setting.
Does this happen because of the memory, when it is not enough anymore?

If that is the case, how can I change it?If that is not the solution, what can I do to solve the problem?
