The things I do ...
Out of the 35 servers, I've just flipped through 19 of them, and I cannot get the doji to be anything but a navy blue doji. The only changes I can get is an open one tick lower on the bar after the doji.
Yes, I do see what you mean - there is a slight difference of one tick, which has changed the bar colour. My understanding is that the data feed cannot be any more than three seconds out from the exchanges, so there will be very slight differences between data providers, giving different bars patterns. But you're not reading just one bar, you're building a whole picture, so it shouldn't matter that much if one bar is a tick out.
It's Monday where you are, and lunchtime, so have a glass of vino on me!
