Hello:
I am backtesting off-line (not in the cloud) and I see this.
20221123 17:58:04.478 ERROR:: MarketOnClose order and exchange not open.
I would think that the backtesting system does not care about the state of the exchange.
In any case the market is open. I do not appear to get any results.
My start and stop dates appear to be within the range of the local data.
It works if I run it in the cloud.
Thanks.
Bill
