Matthew: This APD Looks Odd

Matthew,



I happened to be looking at:



[LINKSYSTEM_27199131]



and noticed it had a small negative APD. It clearly should be positive - based on a back-of-the-envelope guesstimate I did 0.04 looks about right, but not -0.04.



I assume the calc is done after commissions & slippage?



What’s also strange: if you click on the “Best-case, with commis.” option on the chart it looks like there are no commissions, but the stats section shows about $10k worth - which looks about right.



Then if you click “Realism Factor, with commis.”, the blue line looks near enough to horizontal (which may explain the neg APD?). This suggests the Realism is near zero, yet the stats say 100%.



Very strange.



Maybe this system has been re-scaled from $100k to $25k, and has problems??
