How many trades occured in each 1 minute period represented by the OHLC bar?
With a PPS of .0003, could the bid and ask have dropped from .0003/.0004 to .0002/.0003 and the price still be reflected at the Ask, not the Bid?
We have seen transactuon eexcute at .0001 yet the Bid/Ask was .0002/.0003 . Explain that in the chart?
I caution you not to read too much into an OHLC bar chart with 1 minute coarse intervals. You have to do the anaylsis on each trade to determine what is happening.
