Then you understood me wrong. Once again, and I hope for the last time: profit on graph is actual profit paid out to investors. It is amount that investors got.
How do you explain this then:
I run the same exercise but every month from July 25 2018 to July 2 2019, and I get that returns following your graph would have been 10.19% (bigger than if bankroll had been constant since that date, as I previously thought), while I made only 7.43%:
Date Bankroll Profit Capital if bankroll is Constant during the month My investment
07/25/18 1523.63 1133.86 1.0000 1.0000
08/01/18 1549.17 1134.93 1.0007
09/01/18 1526.08 1146.17 1.0080
10/01/18 1527.49 1148.98 1.0098
11/01/18 1515.00 1203.59 1.0459
12/01/18 1447.85 1212.71 1.0522
01/01/19 1486.70 1226.54 1.0623
02/01/19 1496.46 1241.40 1.0729
03/01/19 1476.07 1246.89 1.0768
04/01/19 1440.69 1263.00 1.0886
05/01/19 1385.25 1272.56 1.0958
06/01/19 1382.68 1284.69 1.1054
07/01/19 1285.11 1280.17 1.1018
07/02/19 1285.84 1280.30 1.1019 1.0743
The formula to calculate capital is ((profit at that point in time-previous profit)/previous casino bankroll+1)*previous capital.
For example, for 8/1/18: ((1134.93-1133.86)/1523.63+1)*1
Please read my upper post again and try your calculation again.
