I established the BTC trading model on 2021/8/9 by using Yahoo Finance database of 2021/1/1~2021/8/9 to perform backtest and it earned $116678 per BTC during that period including Long and Short trades. During 2021/8/10~2021/9/12 the model earns $17768 per BTC and it means the model works so far.
did I understand correctly that you did not test this model using real money?
Also, your model is tested only once by your side?
do you realize how uncertain it is to claim "the model works so far" just after one test by your side in a simulation? someone has already suggested it to you, take a loan from the bank and start in real with your method, I don't see an obstacle if you're so sure everything works perfectly.
