Net NEO Margin Position

Total NEO Longs minus NEO Shorts in order to give you the total outstanding NEO margin debt.

ie: If 500,000 NEO has been longed, and 400,000 NEO has been shorted, then 500,000 has been bought, and 400,000 sold, leaving us with 100,000 NEO (net) remaining to be sold to give us an overall neutral margin position.

That isn't to say that the net margin position must move towards zero, but it is a sensible reference point, and historical net values may provide useful insights into the current circumstances.

(Anyone know what category this script should be in?)
