Hi, The value shows 0 ms for "Chart Settings -> Other -> Performance -> Drawing time (Read Only)". Did anything change? It is the same on all my charts. I have a lot of studies on my chart and before you changed to the new Chart Settings screen, I used to see over 100 ms for the drawing time. Thanks. |

Two more questions: 1) For the Volume By Price study with both the start date and the end date being more than a few weeks back, is there a reason it needs to calculate? My study which has the dates of 2020-05-04 to 2021-09-01 is taking 42 ms. 2) I have another Volume By Price study that is marked as hidden. That also takes 16 ms. Are there negative effects if the hidden studies are not calculated on each tick, specifically for the VBP studies? Thanks. |

Just checking back to see if you had a chance to confirm this behavior. Thanks.

This should be resolved in the latest prerelease: The value shows 0 ms for "Chart Settings -> Other -> Performance -> Drawing time (Read Only)". Did anything change? It is the same on all my charts. If not let us know. 1) For the Volume By Price study with both the start date and the end date being more than a few weeks back, is there a reason it needs to calculate? My study which has the dates of 2020-05-04 to 2021-09-01 is taking 42 ms. This represents the full calculation time. It does not mean it is being recalculated every chart update.2) I have another Volume By Price study that is marked as hidden. That also takes 16 ms. Are there negative effects if the hidden studies are not calculated on each tick, specifically for the VBP studies? All studies on the chart have to be calculated. There is no way around this. They have to be.

Thanks. I have a few charts with a bunch of studies in each chart. They all serve a purpose. If I wanted to make my charts more responsive, I have to look at each chart's time to draw and each study's performance one at a time by clicking and navigating through various property screens. I wish, I could get a report of what is impacting my charts' (all of my charts together) responsiveness in a descending order (most impact to least impact). This will allow me to focus my attention on either removing or tuning my studies in some way. Currently, there is a disconnect in the way the performance is reported. If some of these numbers are only for recalculation and the recalculation doesn't occur each update, then I am not getting the full picture of the performance data. For example, a study that recalculates every update and takes 5ms each time has more impact on the responsiveness at the chartbook level than a study that takes 200 ms per recalculation but only runs once an hour. Perhaps, you could consider a way to report how much cumulative time each study and chart has taken in the last 5 minutes or some arbitrary time period you decide. I understand if you don't have time for this at the moment. This can be a longer term goal. The data you report should allow the users to easily obtain (without too many mouse clicks) and see what studies and charts have the highest impact on SC's responsiveness at the chartbook level. In the shorter to medium term, perhaps, you can provide a couple of ACSIL functions (one for the chart and another for the studies in a chart) to report the total performance impact over period of time. If some of this is already thought through and there is a solution, please point me in the right direction. I appreciate your time and attention, thanks. |

I know you guys are working on a lot of things. It is fine if this doesn't fit in your immediate priorities. Just checking to confirm if that is the case. Thanks.

On version 2383 all my charts drawing times values are equal to 0.

We will check on this as soon as we can. Update: We do see the Chart Drawing Time is updating on the Performance tab of the new Chart Settings window.

Anytime I check the performance tab the drawing time only reads 0 ms. The draws per second and calcs per second do update though. Could you please look into this? Version 2384 (OpenGL Enabled).
