I don't fully understand the value add of these Square Arrows. From my understanding of the thread, Xard suggests paying attention most to these square arrows when taking trades in certain directions. So if a blue square arrow appears, time to look for long opportunities, if red square arrow appears, time to short.

But as you can see in the trade I just took, these arrows repaint, and the red square was previously located on the previous local high, until the high was broken and the square arrow is now being shown on the current highest candle. If I were to take that square arrow as a signal not to trade, even though the rest of the indicators say go, I would not have made this long.

Am I missing something on how to properly use these?
