Until recently I have only paid casual attention to candlesticks in my trading but I got interested a couple of weeks ago after reading a post and have been looking a little closer. Yesterday I had three different charting platforms running simultaneously and lo and behold the candles were different on all three. What looked like a doji on one platform had a fairly large body in another. I know Nihaba and a couple of others give a lot of significance to these candles but how do you know your candles are accurate? I would think that daily candles would match pretty close but it appears to me that as you shrink the time frame, small delays in data could alter your candles significantly and make them much less reliable.
