Join club EWI and read the free tutorial first. It's basically an online version of Elliott wave Principal. IMO, it is well worth the money to subscribe to EWI services for a while. Reading them regularly, for at least a few months, is probably the best and most cost effective training available. But - would not advise to follow them (or anyone) blindly in trading. Use your own judgement.
Another word of advice, especially if you read EWI. Always give a lot of weight to the prevailing trend. E-waves have a tendency to make you look for "completed structures" and too expect reversals. You will find that a lot more often waves will just keep subdividing in the direction of the larger trend. Big, important reversals will happen, of course.... but they're just too uncommon to make looking for them a worthwhile effort.

Watch out! Sometimes, ever changing combinations of unrelated cycles may appear to the human mind as a wealth of "meaningful" patterns.... :)
