sabgto: You don't need a broker account - Zorro just found that 2013 price data is missing. We'll upload it in short. Until then you can prevent the message by setting EndDate to 2012 in your scripts.

Maurizio: I'm still not sure if I understand the problem. Did Z12 continue trades from different systems, and then close them? Or did the trades just close by themselves, unrelated to Z12? The latter would be normal, as the recent price movements caused by the fiscal cliff issue would have stopped out many trades. The former would not be normal, as Z12 can not continue or close trades from Z1 or Z2.

Hello, Z12 did not continue trades from Z1 and Z2 traded separately. I did non allowed the system close previous trades, but when I restarted Zorro (new version with Z12) all the previous Z1 and Z2 trades closed by themselves. Anyway, do you think it is better to install future Zorro versions in the week time when market are open and possibly not in the week end?
Thank you

The continue mechanism stores the state of trades in a file in the Log folder. It's Z1.trd for Z1, Z2.trd for Z2, and Z12.trd for Z12. So Z12 can not close trades from Z1 or Z2, even if it wanted, because they are not in the Z12.trd file and thus Z12 does not know their trade ID numbers. Therefore I assume not Z12, but their stop loss has closed those trades.

But to be sure, can you check your Log folder for the 3 files Z1.trd, Z2.trd, and Z12.trd, and post here their file lengths and dates?

- It should not matter at which day you install the update, but it's better to start Zorro when the market is open.

Hello, I think it would be better that I post the log files, so that you could see what exactely appened. How is it possible to send attachments here in the forum? Meanwhile I will try to send the log files by email post. Thank you.
