What is the best way to draw a line extending exactly 5 Slots into the future? The best option I have found so far is to GetTimeBySlotIndex, and then to GetXByTime. That is less-than-ideal for my use case, because my results have the end of the line moving. It looks to me like this is due to the variable time stamp associated with future tick bar slots and probably relative refresh rate. I see functions to get SlotIndex by Time or by X, and to get Time by SlotIndex, but nothing to get X by SlotIndex. I can only get X by BarIndex or by Time.
Details of my use case: I add a 2nd data series (same instrument, primary bars 500-tick, secondary bars 2500-tick) via script, get an SMA value from the secondary data series, and then use RenderTarget.DrawLine for that value. I want to draw the line out into the future covering 5 bars, at which point I will get a new SMA value and therefore a new line. My starting SlotIndex is the 500-tick bar that aligns with the completion of the 2500 tick bar. I add a value to that slot to get the future slot, and that is where I want the line to terminate. Everything else about the script is working fine, except for the endpoint of the line. I would rather the endpoint would be fixed, just as the startpoint is.
