How to deal with splits in live trading?

Hi.
I have a few strategies in live trading mode. Two of them made an order with WLL stock on 8th and 9th of November. The company WLL did the split.

And I saw a huge drawdown on my performance chart (see the link below). The profit has been ok on the next trading day, but metrics and performance chart have this drawdown. I think it's unfair and it has an influence on my position in the leaderboard. Probably, this drawdown should be removed.

How to deal with that?

Hello Sergey,

It looks like we received data for WLL's split a day late, as it is now being correctly applied on 11/09 by the backtester.

For the contest, our general rule is to not retroactively adjust for data, bugs, or other issues encountered during execution. All contestants are using to the same data and platform, bugs included, so we enforce this rule in order to keep the contest fair for everyone. Unfortunately, bugs happen in all software.

I hope you understand why we have this rule, and we are sorry for any inconvenience. We work hard to both keep the contest fair, and to prevent these issues whenever we can.

How you will select strategies to allocation or getting prize when strategy contains a huge drawdown, but it's not true?
