How do you determine the optimal position size for each trade?

For me, for example, it was once a very difficult topic, because I thought that it was possible to invest a fixed amount in each position and that was all, but later it turned out that for each transaction you need to select a separate percentage of the balance in order not to lose all the funds. For example, I have this now: I first review how volatile the asset is, if it is more than the average, I allocate less than 5 percent to the deal, because if I lose it, it will not be so noticeable. But then in order to recoup this loss, I need to find a deal on an asset where the volatility is not so high and in the result of which I will be confident, and then I open a deal with a ratio of 1 to 3
