I never use any of the built-in position functions (currentcontracts,
entryprice, exitprice, marketposition, etc). The problem is that they
don't update until the bar after the position is filled. And systems
only update on the close of the bar. So, in the example above, on daily
data, you could get

Monday - issue the market order
Tuesday open - fill the order
Wednesday close - the position functions update

Better to code your own vars to keep track of that stuff. You can use
"open tomorrow" for backtesting but it obviously won't work realtime as
you don't know what the open tomorrow will be.

Sorry, no more time today. I'm long the emini and feeling the heat. :-)
