Dear All,

I got the below code for drawing Fibonacci lines into the chart from this forum. This Indicator will help me to draw the Fibonacci automatically based on last 100 Candle High Low, however I required your support to modify the coding to draw the Fibonacci lines based on last 100 - X candles (say 15).

Also this code does not draw the Fibonacci Extension levels, please help me to draw the same automatically

Could you please help me to fix this.

For this issue:

"I required your support to modify the coding to draw the Fibonacci lines based on last 100 - X candles (say 15)."

Just change the value in the look back.

Eg, in your example, you want to draw 100 - 15 == 85 lookback, then set the lookback value to 85 so it'll only be based on the last 85. If you want it to only do the last 15, then set the lookback parameter to 15.

There isn't any code modification required for that.
