And why not? If this system is as good as you say it is, run it through a blockchain and you may get 1 million buyers at 10 each!
I'm sure you will find buyers. Plenty of systems out there that don't work but keep the owners from eating beans for dinner.
Your past system statistics are taking from backtest I presume? If this is the case, then the answer is 'no'. Otherwise, is your system taken long positions only?
your proposal wouldn't work. because you failed to provide lots of vital information. perhaps you can partner with another user. when the user earns $$$, the profit will be spitted 50/50. when the user loses $$$, loses will be spitted 50/50 with a cap of say $1 m. Of course, both of you have to get the lawyers to get it finalised.
Okay, you say no slippage, trading it live? So, are you actually, putting in six figures in your trades or that is your total capital? Can it handle millions per trade? Scalability should be everyone's concern. If the hedge funds cannot run millions thru it, they probably, will not bother with it. You may have a niche that you can use to make lots of monies. However, it might not be practical to others if you are looking to sell it.
A system going long using leaps goes a long way the returns you describe. Obviously statistics on drawdown and volatility need to be provided, returns alone are meaningless. Just run it next to your dayjob. You need patience, but the satisfaction makes a lot up for it.
Retail Algo traders make 30% usually. Maybe if your system could stop a drawdown and then revise itself automatically. Like an out of character detector(market is schizophrenic).
