There are different ways to do it. Ideally you look for the perfect places to sell the perp. . . . but many times it is simply my position that determines it.
For example, I started covering short perps way to early on the last move down. . . I started and at 6890 and bought on a scale down to 6780 to where I was 20% over my core long position. . . . (I vary my core by 20% plus or minus). . . as the market continued to break and before I recognized the unique open interest situation that confirmed we should have an explosive move to the upside. . . . I sold back the 20% at a small profit.
However, after recognizing the open interest situation I pulled all my orders to sell on a scale up because I realized they were too low. . . . so stayed 100% long. . . the bottom line is your position always trumps funding. . . . I have found it is best to ignore funding completely when making a market decision . . .
Hope this helps.
