Dislikedi looked at the daily average for g-j when +/-50 entries worked best, and then i thought i should apply a directly proportional straddle to the other pairs. so i divided g-j daily average with 100 (2*50) and it gave me 2.25; then i picked other pairs and i divided their daily average by this, and i got the straddle value for every one of them. obviously, i can't use a +/-50 straddle on e-usd; but +/-15 (which is ~ 67 daily average / 2.25 /2) works better, at least on a visual check. i adjust this value every day, depending on the daily average value.
i don't know if this works, but i'm giving it a try.Ignored
