Saying that you should not lose money is a worthless statement; saying it capital letters does not make any more worth considering. Saying that you want to trade short term price fluctuations without losing money is like saying that you want to be a professional boxer; you just don't want to get hit. Harmonic patterns have been around since long before OTC Forex markets were made available to the general public. If harmonic pattern trading was of any genuine use, everybody would be wealthy. Everybody( commercial and retail) would be looking for bats and crabs, etc. Email any trading professional or institution and ask them what they think about harmonic patterns. The larger Futures Brokerages (amp futures for instance) have auto traded 3rd party systems for years; ask one of their consultants about the long or intermediate term success with harmonic pattern trading. Trading harmonic patterns is like most anything else - it works when it works and it doesn't when it doesn't. Think about it; if harmonics were the path to successful trading who would take the other side of the trade when one of these patterns setup. There algorithms in the market that fade everything : new highs, new lows, breakouts, and yes they would also fade harmonic patterns. The idea of losing money on a trade is not something that anyone wants to do; I doubt that you'll ever be successful until you learn to function in a working environment where in failure is a very real possibility.
