I am currently using SC version 2268 with CQG WebAPI data service....and NASDAQ-100 futures (June and September contracts)

I have been using the "copy chart drawings" from one chart to the other. Specifically, I have a 10 second chart and a 1 minute chart within the same Chartbook. I simply place a Cycle Lines drawing (and Vertical Lines) on the 1 minute chart using the drawing tools, and I then have those lines copied onto the 10 second chart via the Chart Settings Advanced Settings 2 tab.

This had been working perfectly on the June Nasdaq futures contract. But, today I switched to the September contract and a problem has appeared. Specifically, the Cycle Lines within the September contract no longer hold to the same time from the 1 minute chart to the 10 second chart....they time slip slightly as the day progresses. The Vertical Lines drawings DO HOLD the same time from the 1 minute to the 10 second chart without any time slippage....only the Cycle Lines show time slippage. AND I HAD NO PROBLEM WITH THE JUNE CONTRACT HOLDING THE SAME TIME FOR CYCLE LINES FROM THE 1 MINUTE CHART TO THE 10 SECOND CHART....NO time slippage for the June contract.

I have attached an exhibit of both the June contract and the September contract with highlighted explanation/example along the bottom near the time scale. Both of these contracts are identical timeframes and are set at the same exact times in each chartbook so that you can see what the issue is.

Why did the June contract work perfectly and the September contract does not? I did try the reload and recalculate function...but no help.

Another discovery....seems that the Cycle Lines do not have any time slip on the lower timeframe chart as low as a 20 second chart. But, at 15 seconds and 10 seconds the lines do a time slip. Very frustrating!

I also updated to current SC version (and I installed previous version) which did not help. I deleted the September NQ 100 intraday file and reloaded a new September NQ intraday file...which did not help.

Just to make sure, did you Rollover the chart from June to September (and also rollover the drawings), or did you open new charts and put on new drawings?
For the most reliable, advanced, and zero cost futures order routing, use the Teton service:
