Sorry if this is not very related to trading, but I need opinions from traders so I'm posting here.
The attached picture shows my performance at the blackjack tables, plotted with Excel. Each dot represents my "P/L" at the end of each session.
This represents 4 months of cardplay and about 300 sessions.
Net balance is + $12,178
I use a default bet size of $5. And I increase it when I have a winning streak. The largest bet size was $250 on a very good streak.
Comments are welcome. I'm hoping to hear from experienced system testers.
I think a cumulative equity chart would give a clearer picture. For example if your equity chart constantly see-sawed between up a few grand and down a few grand and you happened to present your data on an upswing then i would say it would show no edge. But if there is a smooth upward slope with hundreds of data points it would be interesting to see.
but that is speaking as trader. I know little about blackjack but unless youre counting cards the house has a statistical edge over you and bet sizing wouldnt change that... well thats my understanding.
