Is Start() called after each tick?

I am using the strategy tester to cycle through a few days worth of data with a 1M scale and I have the following line in my Start() routine:

Print(Ask);

I expected to see a Journal entry for each and every tick. When I start the strategy tester with a slow playback setting, I see the chart updating but I do not see the Ask price being printed to the Journal very often. The Ask price is only sent to the Journal about once every 15-30 minutes.

Why is this?

Is it possible to create another tab in MT4 or a debug window in the editor to which text can be sent?

Thanks,
