Is there a way to cause chart updates with ACSIL?

Is there a way to flag that a study/chart/subgraph has changed? So that referencing studies (like study/price overlays) update correctly? I see sc.EarliestUpdateSubgraphDataArrayIndex but I cannot find any documentation on this. Context: I wrote a study that makes subgraph replications of Line tool lines (Ray's). I then use a Study/Price overlay to copy these 'line' subgraphs from my 1 minute chart to my renko chart. This works really nicely. The lines appear correctly warped with the renko blocks. It means my trading study on the renko chart can see the line subgraphs and trade long/short against them. The problem is that the Study/Price overlay doesnt update unless I select Chart->Recalculate. I had some limited success with sc.EarliestUpdateSubgraphDataArrayIndex by always sending a decrementing value. But this doesn't seem to be 100% reliable. The only reliable way I can force an update is by manually selecting Chart->Recalculate. Is there a better way? Thanks again for your help. -Jason |

Yes you do want to use sc.EarliestUpdateSubgraphDataArrayIndex. Set this to the earliest Subgraph array index in the study which has been modified. It is not necessary to set it when sc.IsFullRecalculation is true. It should produce a very stable result when using the Study/Price Overlay study.

How do i know how many times it has been calculated a study during a bar? The study only recalculates with each variation of the price and at the end of the bar?

Thanks for your help earlier. It worked! I've attached a pic in case you're curious what it looks like. The top chart shows the renko projection of the ray (in orange and black) and the bottom chart shows the original Ray on a 60min chart. The study is actually added to a 3rd offscreen 5min chart to make sure it gets good resolution. I do the projection there and then let the study/price overlay project the 5min subgraph onto the renko chart. Each orange/black segment is 5 mins. Thanks again for you help -Jason |
