This is only for profitable traders that have at least of one year of trading with real money. If you were to sell and train someone your strategy. How much would you sell it for?
I have been trading almost 50 years, and I have used various computer strategies about 18 years. Currently, I trade a strategy (live) that has made 21% profit in the most recent 3 months. It trades only four equities, at most once per day, and it goes long only. Given that the markets have been mostly down during the past three months, I'm happy with 21% profit.
I would sell my strategy for $100,000. A person trading an account size of $200,000, should recover his cost and make an extra $60,000 or so in the first year. This is not a guarantee.
I have back tested this strategy going back 5 years, and it was profitable (647%). These figures include all commissions, slippage, and fees. I have not tried to sell it, but I don't think I'd suffer any damage if someone else were trading it besides me, so yeah, I'd sell it.
The strategy runs only on TradeStation, but it is so simple, you could trade it on any platform by making a simple calculation every day, and trading accordingly.
I tweet my trades the day BEFORE I execute them. See @RandomFour on Twitter. I also have a YouTube channel, but I have not shown this strategy on YouTube.
