Hi Jcl,
There hasn't been an internet interruption as far as I'm aware of.
But even if there was an interruption, Zorro should say No connection , the plugin should throw an exception, and should not assume that position was closed.

After zorro assumed that positions were closed , it opened again the positions, because the strategy is made to open new positions when there are no positions open. And now there are double position open in TWS.

The good thing is that is a demo account
