Switch to next market if current market turns in play

[Trader_Tom]

Hi everyone. I've tried to figure this out for myself but I've not had any luck. I'm not sure whether it's because it's not possible though. Hence the post!

I'm wanting to set up an automation rule that switches to the next market in guardian as soon as the current market turns in play. It's for screen recording horse racing markets.

Can anyone shed any light on this?

Thanks in advance.
