I want to hedge with the ZARJPY and EURZAR currency pairs, I want this to be a 100% hedge (or very near at least) as I plan to profit off the swap which are good for these pairs.
The pairs seem to constantly have a correlation of -90% or below, so I’m convinced this method of hedging can work (sell on both pairs).
I have one problem, how do I determine what sizes each lot should be for each pair, as the pip value and the volatility is different.
How would I calculate the lot sizes so that if one pair moves up by £100, the other moves down by the -£100.
And yes I’m aware that spreads are large but this doesn’t bother me as the profit from swaps should outdo this loss in a few days.
