Question about investment allocation in Polymarket.

Hello everyone. I've just started playing Polymarket recently and find it very interesting for predicting various events. However, I'm starting to wonder about capital management. Sometimes I'm very confident in certain markets and want to invest a lot, but other times I feel somewhat in the middle and don't want to invest much. When I think about R:R like trading stocks such as $NVDA, Polymarket doesn't have a clear Stop Loss, and there are many markets to play simultaneously. I'm starting to be unsure how to reasonably allocate funds to each market without overtrading. Do you guys have any principles or proportions for investing in different events? How do you usually divide your funds? I'd appreciate some guidance.
