stoch mom index

[hmmaru]

I have managed to modify you code, to accommodate the Buy/sell signal on the price chart.
This is a second script executed independently. this works fine.

What I want to do is display the value of the price underneath the buy/sell signal when this cross over happens.
Is it also possible to write the time and price value when this happened, to a file ?

have a great day,

thanks again for your help once again.

Hello Harish,

You can use drawTextRelative() to display the price next to your signals. Here's a link that explains how to write info to a file using the File Object.
