Larry, IB would not be the best datafeed to use for tick charts since IB does NOT provide every tick. There is a frequency cap on the datafeed. Thats fine for regular candlestick or OHLC charts, but TICK charts depend on seeing all the ticks.
well,,,,,,it has been 2 years since i last asked....anyone figure out some ratio formula to create some type of" tick" charts using the IB data feed??? thanks
