Huh? What do you mean with real time graph? Pofits with buy and hold obviously equal price development. +100x price development = +100x profit. What should be simulated about that?
The only thing that matters is future profits.
Decide on your algorithm
now, and come back in a week (.. month, or year) and tell us how much it actually could have made.
It is trivial to find and algorithm have
would have traded for immense profits historically. I know if could do much "better" than what the author published above, only by following known fixpoints. But that strategy would not own me even a millibitcoin in the future.
And netiher would the author's. Or...? The proof is in the pudding, as they say.
