Every tick without bid/ask prices

 

Hi folks,


I use to run backtests only in "Every tick based on real tick", but I was checking the database of my broker and I found that Bid/Ask prices are very unsatisfying, there is much much less data about it comparing to "last price" data.

So, I would like to know if there is not Bid/Ask data, is it necessary to run "Real Tick"? Or if I run only "Every Tick" I will get a satisfactory results.

I can't find documentation explaning if "Every Tick" backtest will use all tick by tick data from "last price".
