Hi, I am a first time poster. I am trying to figure out the expected value for a hypothetical stock market trading system. I don't know if this question falls under basic algebra, or statistic, or what, but here is are the inputs:

Total business (trading) days in a year: 252

Size of average profit: $2020 (10 times larger than the average loss)

Holding time / length of average winning trade: 3 days

Size of average loss: -$20

Holding time / length of average losing trade: 1 day

Total number of investable / tradable opportunities (entry signals) per year: 126

Percentage of trades that make a profit: 40%

Percentage of trades that incur a loss: 60%

Extra info:

All profits are reinvested seeking compound growth.

Total risk per trade: 3% of total capital (adjusted constantly to remain at 3%).

What would be the expected value of such a trading system for every one-dollar put at risk?

And if you have time... is there an excel formula I can use to create a spreadsheet for the data (assuming we start with a balance of $10,000)?

Thanks!
