Here's some explanation
S1: 1085 = Net Profit of Strategy S1 since I started this thread
S2: -300 = Net Profit of Strategy S2 since I started this thread
S10: -280 = Net Profit of Strategy S10 since I started this thread
S12: -144 = Net Profit of Strategy S12 since I started this thread
S70: -69.5 = = Net Profit of Strategy S70 (new strategy) since I started this thread (this strategy started trading this week)
Weekly Performance:
2663 = Net Account Value change since Friday last week
S&P 500 Weekly Performance:
4856 = If my whole account would be in SPY (buy & hold), it would have changed that much since last week
Overall Performance since launch:
812 = Overall Performance of all my trades minus commissions since I started this thread
S&P 500 Performance since launch:
1321 = Overall Performance if my whole account would be in SPY since I started this thread
Risk Free Checking Account Performance since launch:
201 = Return would I put my money into a 1% checking account.
In theory you should be able to take S1+S2+S10+S12+S70 (net profit numbers since inception) and they should add up to the overall performance since launch. In reality I sometimes forget to record small S1 trades (S&P Futures strategy), so that's why the numbers don't add up completely. One additional note is that my net liquidation value of the account is based on IB's portfolio margin calculation which changes based on the time I pull the results.
I hope this explains it, if not let me know.
If you're asking how did the week look like to make up the 2663, here are the daily results:
Mon: 894
Tue: 1720
Wed: -1254
Thur: 934
Fri: 369
