Gold made a nice uptrend on M30 and gave 2 good entry signals. The entry signals are V-formations within the reversal zone which is the area between the green lines.
In the area of the big red X the trend was not indicated as strong by the indicator. Right of the big X the blue and orange line started leading the price strong. This tells you that the strength of the trend is good. During this area entries are allowed. Therefore, you could have entered after the rejection at the two green arrows.
Within the area of the small X entries are not allowed. Although the trend was indicated as strong by the blue and orange line, the two green lines (the reversal zone) was no longer there.
