Would this work
Hi All

I've had a moment, and I can't quite work out if this would work

When you place a rollover cash bet with D4F, they charge or pay you interest overnight. If your long, you pay them and if your short, they pay you. The same doesn't apply to quarterly trades.

So my thinking is.

Long FTSE futures March 2004
Short FTSE Futures Rolling cash bet

The net result will be the same, as your trading the same instrument off 1 long contract vs 1 short contract. At the end of each day, D4F then pay for holding your short overnight.

This seems to good to be true - What have I missed
