Good day, I would like to ask, what is the difference between 2nd dot after the arrow and the first second dot after the arrow?

Also the start bar to check for semafor, ignore opposite 2nd dots bar,, and also bars to check, is the parameter correct?

Do you have an example? Thank you very much, trying to figure out.

The difference is whether the signal is displayed every time a 2nd dot appears, or only on the first occurrence.

“2nd dot after arrow” displays the signal every time.
“First 2nd dot after arrow” displays the signal only on the very first occurrence.

It is not possible to judge whether the parameter settings are correct or incorrect.
Semafor recalculates and redraws itself.
The parameter settings vary depending on what kind of signal you want.
Also, unlike human visual judgement, when using an indicator, numerical period values are mandatory.
As shown below, the parameters need to be adjusted according to the trading strategy.

Regarding “Start bar to check Semafor”:
For most trading strategies with other indicators, this would be set to 1.
The function is clear: once the previous candlestick is confirmed, the signal is displayed based on that situation.

In the case of Semafor, since it recalculates and redraws, some ingenuity is required.
For example:
If you want to exit immediately when an arrow appears, set it to 0.
If you want to delay the provisional confirmation of arrows or dots, set it to 1 or higher.

Setting parameters for indicators that recalculate and redraw is difficult.
If the value is small, false signals increase.
If the value is large, signals become delayed.

Regarding “Ignore opposite 2nd Dot bars”:
For example,
when a down arrow appears and a downward 2nd dot is also displayed, a down signal is shown.
However, an upward dot may appear immediately afterwards.
In that case, the down signal would disappear.
This parameter is a workaround that sets a period during which such opposite-direction dots are ignored, preventing the down signal from disappearing.

Regarding “Bars to check”:
This sets how far back in the past the indicator checks for the presence of arrows.
If the period is too short, the signal cannot be determined and a flat signal is produced.
