I am using the "Volume Weighted Average Price - Rolling" - The session times are set correctly - This only stopped working when SC had issues with the symbol data structure - this was sorted when I rolled forward to 1366. It was working before I 'upgraded' to 1366 - Please advise |

To clarify - the data is now working, both intraday & historic but the Rolling VWAP is not

This is operating correctly. When using a Time Period Type of Days, trading days are used to determine the rolling periods. The start of a trading day is determined from the session times, and yours is likely 00:00:00. A Time Period Length of 1-day is not very interesting as there is nothing to roll over, since the period is always a single day. Were you trying to achieve a 24-hour rolling period (vs 1 trading day)? In the next version, we have added "Minutes" to Time Period Type. For rolling 24-hour period use 1440 minutes.

I don't understand - This was working OK before I had SC data issues - Rolling means look back 1 day (same time previous day and calculate not calculate at start of day (this is the standard VWAP study). As per your response a 1-day rolling period = 24-h = 1440 minutes - please advise

This was recently changed to be consistent across different studies. Days implies trading days. As mentioned, in the next version you will be able to use minutes to achieve this.

Why change this? can you please send me the previous version as it worked as described i.e. not resetting every x number of days but a continuous rollingperiod.

Excellent example when we try to satisfy one user, we get another user upset. We cannot win. So we end up going going through an awful lot of work to satisfy one user and have to go through even more work to satisfy another user, and write up all the documentation and answer all of the related support. It only goes to show why sometimes we are abrupt on this board and say no we are not going to add features requested. Sierra Chart Support - Engineering Level Your definitive source for support.

OK I understand. I have worked in SW development so appreciate your dilemma. Can you send me through the study code for the previous version. I can add as a custom study.

Thanks I really appreciate your flexibility. Could you mail me when it's included in a new release as I don't regularly upgrade to new versions?

noticed you mentioned adding the old version functionality...i know you are busy but could you attach the .cpp of the old study so could use as a custom? or just have a second rolling vwap called 'old version' or something like that thanks |
