ok well that makes for a lot of complications. For example, are the invisible "tick candles" evenly spaced just like they would be if it was a tick candle chart? If so, displaying the tick lines would be difficult and a bit inconsistent visually, since they would have to stretch/squeeze into the candle widths.
Alternatively, if tick lines were displayed time-based, but only the indicators were calculated on the "tick candle" points that were not evenly spaced, that would be even more difficult, because internally the whole machinery is set up to be on evenly spaced points.
