Post From: Inconsistent data between leaving Sierra open and closing it only to open an hour later.

I'm using CLEM with default chart settings and using an automated trading system with a basic VWAP StdDev formula.

If I leave Sierra open it takes DIFFERENT trades vs leaving it closed and open it only 1 hour later

EG.
I make TWO copies of the Sierra folder A and B
1. Open A and let it trade for 2 hours. It takes a long trade via signal at 09h50.
2. Close A
3. Open B and let it "download historical data" and catchup ONLY the last 2 hours.
4. B's long trade happens at a different and better location at 10h05. A's signal doesn't show on B's.

Running a replay on B from 08h00 shows it does NOT take the same trades as A.
Using Trade > AutoTrade System Replay BackTest and Replay > Accurate Trading System Back Test both show the same results ie A and B are different. I even run a replay on A and B at a speed of 1x and I get the same results. A and B take different trades.

Immediately the BUY / SELL signals are in different places. A always gets the SAME signals and B gets it's SAME signals.

This is only after 1 hour, how can the DATA be THAT different?

I have tested this on my laptop, desktop and server with NO other charts open. CPU hits around max 2%. RAM has AMPLE 26GiB and host has NVME based drives. Internet is via 20M/20M FIBRE line. Tried this on both Linux and Windows. CQG data. I really would love to keep using Sierra as I have invested loads of time and money in it but these inconsistencies are driving me mad.

Please can someone assist? What am I missing?
