Added ability to ignore arrow bias.

Don't ask for background on adding the feature.
Don't ask if there is a use for it.

Click on the most recent arrow to display an "X" above it.
In this case,
Assume that the arrow is not yet displayed.
The histogram with the changed bias is then displayed.

Click the arrow again to restore it.

If there are other shapes overlapping the arrow, it will not respond.
It is better to use XARD type indicator (XU v65m-XARD UNIVERSE).
Indicators of funchi type (FNC_Semafor) will not respond well.

Explanation of the attached image
On the upper side, if nothing is done.
The lower side is when the most recent arrow bias is disabled.

The "X" disappears when the arrow Semafor is updated.
Note that updates are made every 5 minutes (default).
