The disadvantage of the retail trader concerning technology and software against the big boys becomes bigger and bigger. Hardware power grew at an enormous rate the last 15 years, but when it comes to speed of trading-, backtesting-, scanning software, the improvement rate lags behind. Software makers always try to sell the same concept. If someone comes with a totally new concept, it covers only a small part of trading. Intraday backtesting on ascii files? This is an absurd concept and it seems nobody thinks about a new way. The way to go for the retail trader is discretionary trading (at least for daytrading) or to be a professional programmer and develop everything from the scratch. Please prove me wrong and show me some examples!
