I just signed up for the trial on Scarr. Haven't had a chance to mess with it yet though but I will later tonight.
I've used seasonalgo briefly also, I did the trial on it. It was pretty useful I felt like. Good for coming up with ideas and testing them. I didn't pay much attention to the specific dates they list for the spreads, but the ideas themselves seemed worthwhile to look into.
Good to know there are seasonal in financials and currencies, just find it easier to look for grow/raise instruments as many happen in same months when they are decent.you are wrong. There are certainly seasonal patterns in financials and currencies. Fiscal years differing around the globe being one catalyst for seasonal patterns. GL
