Candlestick sudy - windows

hey guys,
I have a(few) super newbie question : I’ve notice windows(gaps) from the end of one session to the next for timeframes less than weekly each week, and windows from month to month on the weekly charts. Are these windows legit? You know, are they genuine continuation patterns. This question is based on the fact that the markets doesn’t close per se … are windows even common in the forex market?

I use candlestick indicator in my trading platform metatrader 4. It is easy for my to open my position. I also use the parabolic sar to indicate the signal. When the parabolic sar above the candlestick I will open sell and so forth when the parabolic sar in the below of candlestick I open buy.
