The other point i would make is trying to get out for a pip.
There is very real danger trying to get out for a pip in pre open, pre close auction.
This is because algorythm trading is so much faster than human trading, and within 1/100th of a second is able to reduce down the volume just as needed to ensure a low of .002 is achieved.
This has been achieved on 3 out of 4 occasions over the past two trading open and close.
The patient in my opinion will be handsomely rewarded.
