Signal leverageand return

Hi, I have a question. I am trading a private signal which currently has about a 5% avge. monthly return and about a 15% largest drawdown. In the long term (based on past demo account trading the same system) the monthly return will probably go up to about 10% per month and the monthly drawdown to about 20%. However, my leverage is 100:1. I notice a lot of the signals are 500:1. Does that make my signal unviable and uncompetitive campared to others with higher leverage? Many thanks.
