First of all, I want to say, I LOVE YOUR SITE. By far the best trading chart on the web, bar none.
I do have a request though, if you have time to do it/want to.
Add a alert/sound for different user set variables. Could be just for one reason or many.
For example;
- when 'x' crosses 'y'
- when price hits 'v' amount
- when volume surpasses 'w'
- also on the indicators (MACD, etc.)
- etc.
Like I said, just a suggestion. And no matter what, you still have the best site out there.
Cheers and have a good one!
