How can I know my best (or max) total won in a channel?

Hi,

Does exist any variable that tells me what was the max (or the best) total won I achieved in a channel?

Example:

Currently my total won is 100. I won 4$ in a bet, now my best (or max) total won in the channel is 104.

Now I lost in a bet 10$. My total won is now 94, but my best (or max) total won I achieved was 104.

Regards.
