Ya discretionary trading takes into account a lot...for better or worse. I like at least finding out ways to dimension or profile a market......
some people use RSI, Stochastic and MACD. I can't. doesn't mean those studies are useless. Trade simple and stick to trends - I agree. BTW, did you look at intra day VWAP or longer term? if longer term then what program? I'm still looking for it . If short term then I agree with you - not so great.
I downloaded ninja about a year ago and it seemed very not user friendly so I deleted it at once, I wouldn't know to program it anyway.
you can change the period for mvwap... <a target='_blank' title='ImageShack - Image And Video Hosting' href='http://imageshack.us/photo/my-images/255/mvwap.png/'><img src='http://imageshack.us/a/img255/1582/mvwap.png' border='0'/></a><br>Uploaded with <a target='_blank' href='http://imageshack.us'>ImageShack.us</a>
For vwap I looked at all time frames and nothing is really there to work with. Minute, hourly, tick, volume, etc. I do not see any value in vwap from my research.
