How to draw lines between TWO LOWEST/HIGHEST candles among last 300 bars ?
Nobody knows ?
puncher:
I would like to draw automatically on 30 MIN chart two lines (support and resistance) indicated by the last 300 bars. From the last 300 bars indicator should find two MAXIMUM BARS (ONLY 2 HIGHEST BARS AMONG THE LAST 300 BARS) and draw the RED LINE and from the other hand the same indicator should find two MINIMUM BARS (ONLY 2 LOWEST BARS AMONG THE LAST 300 BARS) and draw the GREEN LINE as on the picture.
I wrote an indicator that does EXACTLY what you asked for

But it doesn't do exactly what you want...
From the last 300 bars indicator should find two MAXIMUM BARS (ONLY 2 HIGHEST BARS AMONG THE LAST 300 BARS) and draw the RED LINE and from the other hand the same indicator should find two MINIMUM BARS (ONLY 2 LOWEST BARS AMONG THE LAST 300 BARS) and draw the GREEN LINE as on the picture.
Look at the lines in the chart... They are plotted at the 2 Max and 2 Min bars for the period.
Everything will be OK, but ther is ONE PROBLEM.. I NEED draw trend lines AS:
SUPPORT LINE always UNDER prices (LOW) - current and historical
RESISTANCE LINE always ABOVE prices (HIGH) - current and historical
