You might have heard about this incident: there was an oil futures contract that traded at negative prices due to delivery issues.
Sure enough, there was an unfortunate trader using the Interactive Brokers platform. The platform said it was trading for one cent when it was in fact very negative:https://markets.businessinsider.com...ns-on-brokerage-glitch-2020-5-1029186688
Does Zorro have the ability to trade assets with negative prices? Assume of course that the broker and plugin supports it too.
I seem to recall some shuffled-price curve backtests where prices did indeed go negative - and Zorro denied trading when the price was negative with some kind of illegal price error. In live trading, I'm hoping that I can close out such unfortunate positions instantly and not after I get the phone call from my broker.
And if not, perhaps Zorro should support this?
