High low value Indicator

Hi experts,

I want to see high value and low value of current candle. I know MT4 already show Open, High, Low, Close value (OHLC) on the left corner but it's too small and is not customized. I would like to see the High value on the top right corner and low value in bottom right corner.

I am an amateur in coding. I just modify this indicator base on other indicator. It shows high value and low value as I desire when I attach it to chart but it doesn't not give the update value on the next candle. Could you please help me?

Thanks for your support!

Move the code in the init() function to the start() function.

To be technically correct, you could also change
to this
As the objects already exist for successive ticks.
Ditto for the "Low" label

Also this
is simpler than this
and automatically uses the pairs available digits.

Thanks for your guide Xaphod.
I attach the update version here in case anyone wants to try.

Excellent. It will be more helpfull If you can include the candle 'open' value and give us the option to position it anywhere on the chart. thanks in advance.
