You said:"I understand that the generated ticks will be generated using interpolation (so they won't be exacts)". You are very optimistic, they will not only be far away from being exact, they (the tick data) will be completely removed from reality, the only parameters known for the tick data will be boundary conditions, such as open high low close. You ...


What Tick data you have in mind? NASDAQ ITCH is tick data but you have to construct the limit order book yourself to keep track of the best bid and ask price for each stocks. Not a trivial task. If you get TAQ data, you will get the best bid and ask (NBBO) but TAQ data has some issues like no odd-lot trades and trades are not mark buyer or seller initiated.

That exchange spec implies that there isn't a legal price of 1001, 1002, ..., 1009. The next available price after 1000 is just 1010. If your pricing engine determines a fair value of, say, 1005, then your application will need to apply some rounding logic. For example, you can always round away from the inside price, or you can simply round to the nearest ...


We've done this before (*), but it is trivial: one tick for open, one tick for high, one tick for low, one tick for close. For tick timestamps, open is 08:01:00, close is 08:01:59.999, high is 08:01:20 and low is 08:01:40. (Or if that gives strange results, open is 08:01:00.001 and close is 08:02:00.000; it depends how your system makes bars.) If you want ...
