Ok, then the IDs of those trades are lost since you overwrote the old log by starting the new Zorro session, But you can still identify the trades from their opening dates. Check in the MT4 platform if 2 of the 3 trades were in fact the two orphaned USD/JPY trades. If so, then it's explained why Zorro did not ask you to close the trades. Zorro did not know of those trades.

This is a large number of orphaned trades. We also had an orphaned trade yesterday, but not 3. We'll do something about it in the next Z7 update. Until then it is recommended that you observe Z7 messages and trade list regularly, f.i. on your smartphone if Z7 runs on a VPS.
