I’ve tried to modify the code below “Swing Points By:tufedtm” in term of my desired conditions. since I’m not familiar with arrays and am rookie in coding, may I write what I’m expect may be you can guide me if it’s possible.
The complete code costumed a little bit be myself:

The code works good and shows number of Swing highs/lows =Point_max

enter image description here
As it can be seen, several last Swing highs(Green lines) and Swing lows(Red lines)based on 3 candles are being plotted. What I’m expecting is something like this:

“Imagine there are arrays that keep horizontal lines for Swing highs and lows with length=1 (swing in 3 candles patern) and for max 500 bars ago, but wait and do not plot lines. when a candle closed above the swing high, then, for the first and next confirmed swing high, after that specific closing candle bar, a green line will be plotted, previous broken swing high will be deleted and also a red line for the previous and nearest swing low before that closing candle will be plotted.

Same, if a candle closed below the swing low, then, for the next confirmed swing low after that crossing candle, a red line will be plotted, the previous broken swing low will be deleted, and also a green line for the previous and nearest congirmed swing high before that candle will be plotted. This process is being continued to the current time and that means everytime we only have two lines, one swing high and one swing low but according to mentioned conditions.”

Since I’m not a code developer, I’ve tried several codes and tried to modify them in term of my circumstances, finally I found out Arrays are what I need but I was not succesful in that.
Images below illustrate almost what I’m expecting.
