Have you thought about keeping a record of bets, monthly wins and losses, to track this?.
Is such record-keeping important to you, or do you not consider it crucial for your economy?.
This python script might be an example of how you could do it.
This is crucial especially if you have a lot of accounts in different casinos, I know that some casino give you bet slips and history of betting but when you have an account in another casino meaning you can't all of that on a single app.
I believe not everyone are similiar with the python or even programming language. I mean it would be great if you put this in the form of a website so everyone can access it/

This is important even if you have good economy and trade within a budget
