Would You Accept USD80 for a Confirmed Trading System Bug?
I encountered a bug when placing a vertical spread order. Longbridge investigated and confirmed that it was a system logic issue / race condition, where an earlier response could overwrite the latest option strategy selection.
As a result, the order details became inconsistent with the strategy I intended to place.
I identified the issue and closed the other leg myself using my own options knowledge to mitigate the potential damage. Longbridge is now saying there is no realised loss because the overall strategy currently has no realised loss.
Based on my original trade thesis, the intended position had a potential profit of around USD2,430, while the incorrect position could potentially have resulted in a loss of around USD2,260 if I had not identified and managed it.
Longbridge has offered USD80 as an options cash coupon as a goodwill gesture, which requires me to make another options trade.
I feel that a cash credit would be more appropriate, especially since I had to identify and mitigate a system error myself. I'm also concerned about what could have happened if a less experienced investor had encountered the same bug and didn't realise what was happening.
What would you do?
Note: look carefully at 'buy' vertical spread.
