[Programming Help] - MarketDepth Data updates in ACSIL in Replay simulation does not match bid/ask

I am evaluating using MKT DepthData in AutoTrade Replay backtest, in ACSIL code: - Evaluation account, running for MESU24-CME - Chart has 1min bars - Re-downloaded market depth data - Using replay-based simulation with time increment of 1sec, speed 1920x - Intraday Data Storage Time unit is 1 tick I see bid and ask changing, but the market depth data updates at a much reduced rate, in fact I see the number of levels and the values of level at each depth only changing every 10 minutes (see below, where I print out how many levels have changing data). Is it possible to run a historical replay with the MDP data changing with each call to ACSIL ? Is this just an issue with evaluation trial? Apologize if it was answered elsewhere but could not track it down. Example: I see the bid and ask change within each call and index as expected, but none of the MktDepth entries changes value, e.g each line here is a call to my ACSIL function where I find the MarketDepth bid data and check if it changed sc.GetCurrentDateTime: 2024-07-12 18:00:55.597000 sc.Index: 10411 noBidLevels: 1141 noMktDepthChanges: 0 sc.bid: 5701.75 sc.bidsize: 105 sc.GetCurrentDateTime: 2024-07-12 18:00:57.302000 sc.Index: 10411 noBidLevels: 1141 noMktDepthChanges: 0 sc.bid: 5701.75 sc.bidsize: 118 sc.GetCurrentDateTime: 2024-07-12 18:00:57.476000 sc.Index: 10411 noBidLevels: 1141 noMktDepthChanges: 0 sc.bid: 5701.75 sc.bidsize: 132 sc.GetCurrentDateTime: 2024-07-12 18:00:57.972000 sc.Index: 10411 noBidLevels: 1141 noMktDepthChanges: 0 sc.bid: 5701.75 sc.bidsize: 132 sc.GetCurrentDateTime: 2024-07-12 18:00:58.861000 sc.Index: 10411 noBidLevels: 1141 noMktDepthChanges: 0 sc.bid: 5701.5 sc.bidsize: 53 sc.GetCurrentDateTime: 2024-07-12 18:00:59.620000 sc.Index: 10411 noBidLevels: 1141 noMktDepthChanges: 0 sc.bid: 5701.5 sc.bidsize: 112 sc.GetCurrentDateTime: 2024-07-12 18:00:59.711000 sc.Index: 10411 noBidLevels: 1141 noMktDepthChanges: 0 sc.bid: 5701.75 sc.bidsize: 42 sc.GetCurrentDateTime: 2024-07-12 18:01:00.035000 sc.Index: 10411 noBidLevels: 1141 noMktDepthChanges: 0 sc.bid: 5701.75 sc.bidsize: 90 sc.GetCurrentDateTime: 2024-07-12 18:01:00.194000 sc.Index: 10412 noBidLevels: 1141 noMktDepthChanges: 0 sc.bid: 5701.75 sc.bidsize: 119 sc.GetCurrentDateTime: 2024-07-12 18:01:00.250000 sc.Index: 10412 noBidLevels: 1141 noMktDepthChanges: 0 sc.bid: 5701.75 sc.bidsize: 143 sc.GetCurrentDateTime: 2024-07-12 18:01:01.358000 sc.Index: 10412 noBidLevels: 1141 noMktDepthChanges: 0 sc.bid: 5702 sc.bidsize: 173 sc.GetCurrentDateTime: 2024-07-12 18:01:01.528000 sc.Index: 10412 noBidLevels: 1141 noMktDepthChanges: 0 sc.bid: 5702 sc.bidsize: 78 sc.GetCurrentDateTime: 2024-07-12 18:01:02.194000 sc.Index: 10412 noBidLevels: 1141 noMktDepthChanges: 0 sc.bid: 5702 sc.bidsize: 121 sc.GetCurrentDateTime: 2024-07-12 18:01:02.917000 sc.Index: 10412 noBidLevels: 1141 noMktDepthChanges: 0 sc.bid: 5702.25 sc.bidsize: 130 sc.GetCurrentDateTime: 2024-07-12 18:01:03.096000 sc.Index: 10412 noBidLevels: 1141 noMktDepthChanges: 0 sc.bid: 5702.25 sc.bidsize: 111 sc.GetCurrentDateTime: 2024-07-12 18:01:03.240000 sc.Index: 10412 noBidLevels: 1141 noMktDepthChanges: 0 sc.bid: 5702.25 sc.bidsize: 114 sc.GetCurrentDateTime: 2024-07-12 18:01:03.574000 sc.Index: 10412 noBidLevels: 1141 noMktDepthChanges: 0 sc.bid: 5702.25 sc.bidsize: 116 sc.GetCurrentDateTime: 2024-07-12 18:01:04.151000 sc.Index: 10412 noBidLevels: 1141 noMktDepthChanges: 0 sc.bid: 5702 sc.bidsize: 201 sc.GetCurrentDateTime: 2024-07-12 18:01:04.194000 sc.Index: 10412 noBidLevels: 1141 noMktDepthChanges: 0 sc.bid: 5702 sc.bidsize: 207 sc.GetCurrentDateTime: 2024-07-12 18:01:04.220000 sc.Index: 10412 noBidLevels: 1141 noMktDepthChanges: 0 sc.bid: 5702 sc.bidsize: 209 sc.GetCurrentDateTime: 2024-07-12 18:01:04.348000 sc.Index: 10412 noBidLevels: 1141 noMktDepthChanges: 0 sc.bid: 5702.25 sc.bidsize: 209 ...
