Not claiming alpha or free money.
I was bored and tried making a blackjack-style game where each round = one trading day.
Your “hand” is the last 5 daily closes.
Draw a straight line through them.
If the line slopes up → bet up.
If it slopes down → bet down.
Bigger slope = higher payout.
One round, one day, then reset.
100 → 102 → 101 → 103 → 106
Line points up → bet up
Next day closes higher → win.
Where does this immediately break?
Would you change the payout rules or the window size?
