And therein is the rub. If your 'correlation' was any good, you'd not still be posting here after 11 years and certainly not be posting more than you trade. I've got nothing against moving averages, they are the most pristine of indicators, buts that's all you've got. To try to isolate one specific currency from others using moving averages across an aggregation of pairs for which it is base or counter is futility.
If you wait for Yen to be above a certain arbitrary level and Sterling to be below a certain arbitrary level before entering a trade, you'll be too late. By the time the market 'confirms' what you suspected, it is TOO LATE. By the time the market passes or fails a 'test', it is too late. To be paid, you must act upon your suspicions before they are manifested.
Come on, take me up on my offer to show you how it's done. One pair, one day, you set the hours. I'll show you what you can do and you run your correlator thingamyjig alongside and watch open mouthed as I show you how much it doesn't matter. It'll open your eyes.
