In case of IB, the broker will cancel all open orders when the split or a special dividend happens. This means that if you have an already open trade, all of its stop losses and profit targets are cancelled and you have an unprotected trade. In Zorro, how would I re-issue these exit orders then?

Regarding adjusting historical data...
So when a split happens, would this approach work?
1 - detect an upcoming split
2 - when the market is closed, close Zorro (keep Open trades and keep trading)
3 - adjust historical data
4 - restart Zorro, reloading the session
5 - Zorro re-runs the Lookback period on the adjusted data, thereby adjusting the series <== Would this actually happen???

Thanks!
