Indi Coding

Hi all
I started learning MQL, so hopefully one of these weeks (years

) I can help with coding here.
As I am still in the beginning of tutorials, I can only do very basic stuff, like the "Hello world" to appear on a chart or calling an alert etc.
What I want to ask any coder please,
How do I get the highest close of x amount of candles, and the draw (paint) that line on a chart.
Same with the lowest close of c amount of candles.
I tried Close(120) but it obviously only give me candle # 120's close (And not even a dot on the chart

)
Thanks for the help
Francois

You don't want to use just the Close[] array since that will just give you the close of x shift. What you need to do is use iHighest() with Close[].

So to find the highest close price of the last 120 candles, it would look something like this:

Code: [Select]

Close[iHighest(NULL,0,MODE_CLOSE,120,0)]

Drawing a horizontal line after you get this is simple. You can use the ObjectCreate() function.
