Backtesting with trail stoploss

Beginner Questions
1

Hi,

I am in the middle of backtest process, and would like to see how is trailstop performing. If there is a candle with large wick in the oposite direction of my trade, how can i know what happen first, down move or up move?
In this case order of events determins if stop is trigered or not.I know i can go to lower tf, but that still doesnt solve the problem. Have you ran in a problem like this, if so, how did you solved it?

The only way I know is to look at lower timeframes, or if you are using backtesting software with tick or 1M data (e.g. Forex Tester 2), then just move price forward tick-by-tick to see how the candle forms.
