My sole opinion, when it come to Algo, I almost all the time use tick. OHLC give time frame delayed in accordance to time bar, ie. volume and impulse was spent. Furthermore, OHLC is more into indicator based which time frame of the model is varying all the time in real market (unless you optimize it with certain TF), so no accurate enough in my opinion.
Thanks for your comments.
I agree, with you.
Ninja does have options for a set of secondary bar series to be used as the price data to fill your orders, this allows to bring in more granular data. For instance, strategy running on a 5 min bars, but order fills occurring from a 1 min bars.
I have never bought tick data before.
1. How much does historical tick data cost? 10 years worth of data.
Thanks,
