Help with runner_number please

Hi, 

I'm confused by runner_number: the explanation says "The number of selections in the market".

So if there are 12 runners in a race but only 2 are selected for auto trading (my selections) what is runner_number then? Is it number of runner (12) or number of selections (2)?

Thank you

hi
both are based on the number of runners/selections in the MARKET

The number of selections that have met the criteria of the trigger can be obtained using the matching_number variable.

got it, thank you!
