First of all, thanks for the XARD - great "Simple Trend Following Trading System" and to everyone who takes an active part in the comments.
I read the comments carefully and with interest. I have a question:

- What does the appearance of the white square mean (I guess ready to move, waiting for an arrow to appear)? If I'm right, when will the arrow appear when the two MAs in the case of the picture turn blue, or wrong?

- When do these lines appear (I guess blue for ascending (UP), pink for descending (DOWN)? Will appear when the white square becomes an arrow?

I will be happy for any comments.

Thanks in advance and profitable trading
