The built-in Cumulative Delta study: Repainting problem

[HalTrader]

Hello everyone,

I have observed that the built-in Cumulative Delta study is repainting. This means that the CV Open/High/Low/Close/Delta values for recent historical bars (after the study is uploaded on the chart) shown on the cursor data window (and calculated on DataSeries) are not consistent after I click on "Update" in the study settings, or when I open a new chart (same instrument) on another window and compare it with the previous one. This might be misleading and could lead to an incorrect estimation of absorption or exhaustion (divergence between Price and Cumulative Volume Delta, mostly used by Order Flow traders) since swing high or swing low values for historical Cumulative Volume Delta bars change once the study is updated.

I tested this in real-time on the 1-min timeframe on EPH24 (E-mini S&P 500 March contract). My broker is EdgeClear and my data provider is CQG. I have a second account at AMP with CQG data, and the repainting problem still occurs. I tested it using different configurations: The "Recalculate On Close" box unchecked or check, it still repaints.

Please find attached the screenshots. I have already contacted MotiveWave support. I just want to have your thoughts on this. Could you also please test it on your side to check whether your Cumulative Volume study values are repainting? If so, it would be great if you could also contact MotiveWave support and inform them about this repainting problem. I hope the repainting issue can be corrected.

Also, please find the attached images for "Recalculate On Close": checked

Aha !! I've done work with this Study before, and I had a sneaky suspicion it had issues.

Thanks for that elaborate testing and analysis, @HalTrader !

I will not write MW about this right away, but might do so in the future, when I encounter the issue again during coding

I personally don't use the study, but if the issue is reproducible I suggest sending it directly to MW support. Other users may benefit from the fix.

I think their may be a few issues with the Cumulative Delta study. If you set the Relative delta to show large orders 100+, uncheck aggregate data and watch time and sales, there are no order over 100 but it will still show them plotted.

Hi good folks...

Has this issue been resolved since the OP? I see that the "recalculate on close" checkbox is no longer present in MW 7, and so I'm hopeful that this is no longer a problem, and that it's settled that the Cumulative Delta study isn't repainting? I rely heavily on cumulative delta analysis. Many thanks!

The repainting issue was fixed in MW 6, but I haven't tested it in MW 7 yet. I'll take a look at it later.

As an update, the tech team kindly confirmed your speculation: that it's indeed no longer a thing. Many thanks for chiming in!
