maybe someone will benefit this. the idea is to find the Square when you open your chart and plan your trades oppisite of the Square until there is established 2nd dot.
once you find your square you and find the dot which xards calls 2nd dot for the first time but there will be dots until the cycle completes. maybe the picture can explain better. i am using 1M TF for the sake of the exmple you can use whatever TF you prefer the idea is find your way around the 2nd dot and cross of the trend and signal line.

Edit if you check now at bottom there is Square but this one has not established the 2nd which in our case will have changed our direction depending our TF of trading ideally the 15M TF. see the 2nd image which just shows how the cycle works the market continues the trend in the established Square and we will keep hitting until we find Square with stablished 2nd dot and cross of both the trend and signal.
