Post From: saving intraday data from live feeding

The specific issue is with custom studies that use Time and Sales data (sc.GetTimeAndSales() and sc.GetTimeSalesArrayIndexesForBarIndex()). These studies calculate correctly during live market hours, but when I reload the chart or restart Sierra Chart, only the current session's calculated values remain - all previously calculated values from prior to the reload disappear. I have a custom study that counts ask transactions using the Time and Sales array. The logic works perfectly in real-time, but the calculated results don't persist. I'm using basic sc.AutoLoop = 1 and storing results in sc.Subgraph[0][sc.Index]. Question: Is there a specific Sierra Chart setting or code pattern required to persist custom study calculations that are derived from Time and Sales data? The underlying T&S data isn't available to recalculate previous sessions, but I need the calculated results to be saved in the chart file. I have older custom studies (from previous SC versions) that successfully persisted similar Time and Sales derived calculations, so I believe this should be possible. What am I missing in the current version? |
