Connors RSI Test —由samtsui 提供的指标

Re Fade2Black request:

The indicator needs to use Connors RSI on candle stick charts.

It basically needs to give an alert if the candle stick closes even or up but the Conors RSI closes down more than 3 points.

Here's a pic showing..

And on the flip side I also need it to give an alert if the candle closes even or down but the conors rsi close up more than 3 points.

Like this..

I hope I've explained myself well. Let me know how much you'd charge for this.

Thanks
