Actually I was just thinking, how it may happen.
So when restarting Zorro with already open positions, cancelling the restart before the resume happend, Zorro saves the actual trades in the trd file, so it saves the trades of the last run, which is before the resume of already open trades, basically having many open, saving 0 open, then thery are lost.


So in my case, if my suspicion is right, server didn't answer in time for the actual prices, skipping the price download.
So restart was needed, which maybe resulted in overwriting the trd file.
