I am going to stop posting all these intraday trades and gather them ~ once an hour.

Something weird just happened, maybe a data problem. These kinds of jumps back and forth don't happen in OFV that often. I need to start logging all inputs to a db to debug.

POFVF has been above and below SPX - do you have any strategy on exiting your short position or are you just hoping that Iran blocks the Strait of Hormuz so you can get back to BE?

SPX, 1328.03. FV, 1134.04. OFV, 1324.29. POFVF, 1314.29

Through the entire day, SPX and OFV have been very tight. This is the first time today that they have deviated this "much".
 
Exit at close:

02/01/2012 16:00:00 OFV = 1321.40675126637 Buy SPX at 1324.09

Not surprising, today was about a break-even (+3.20 excluding commission and slippage) day since there was very little to work with from open to close. There was some weirdness in the data that probably caused the 5 point loss, but that is the reality of trading (potential data and software problems), and it must be taken as part of the simulation.

One thing that gives me great confidence, although from a very small sample, the system that enters only on spreads > 2.50 has not had a losing trade, and is up almost 10 points. It is still correct to run a mixed strategy of the crossover + the wide spread, because I think if done right they will smooth out the equity curve. The only problem with he crossover system is it generates lots of commissions on tight days, and has to pay the spread to get in and out. still, it even if it loses a little, it will keep the other system from losing big.

Cross Over System:

Day 1 PnL : 6.49 Points
Day 2 PnL : 3.55 Points

I will start keeping track officially of the wide spread system soon too. That one is up ~10 in addition to above.
