Yes there are but it depends on what really you looking for ?
As it should be like a complete package for the strategy you looking to work with !!
You say it wrong 100% Hedge = dont not equal to Zero
Let me Explain for you
when you buy 1 lot for Margin 100$, and than sell 1 lot for 100$ Margin (Hedge = Zero) which is 0% Hedge not 100%
0% hedge = Zero
25% Hedge means you Pay 1/4 from the 400$ = 100$
50% Hedge means you pay for 1/2 the the 400$ = 200$ (or consider still as 1 lot)
100% Hedge means you pay for the 2 complete lots 400$
Hope this helps you.
