Regardless of whether currencies are your thing, this is 10 quid well spent for any trader:
FXCM Power Course
This really introduced me to the concept of going for bigger moves, risk/reward, and most importantly, only taking entries on your own terms. In fact it has fundamentally changed the way that I trade and I owe it a lot of money.
Having been on a similar 2 hour free course from Darren Winters I can tell you that the only thing you will learn is how great his course and related products are. I only went out of interest as I already had a lot of experience and so wasn't tempted but sadly many in the room the room weren't so lucky.
Of the others, I have personal experience of
John Barlett and
Robbie Burns.
John (£350) is aimed at a very basic level, which might be what you want. I was a bit disappointed but at least he is reasonably priced (with one of his discounts at least) and honest.
Robbie (£390)is more advanced and puts on a better show, though aimed squarely at equities in long timeframes. His clientele is a bit more astute and there were some full time traders there who had some interesting stories. I don't generally pick individual stocks but he will save me a lot of money in the future. His book is worth a read too, regarding the UK stockmarket.
Lastly,
David Jones is supposed to be extremely good value, especially if you have a CMC acount as you can do all 3 days for about 400+VAT. This would be my recommendation if you really want to do a course (and I don't regret doing the ones I did). £400 is nowt in a trading life and if it saves you from one dicky trade then it has paid for itself.
