TDI modification & notification

Hi guys! I am willing to pay a little for your service.

I have a TDI indicator. In case you don't know the indicator I'll describe a little:

My simplified version of the TDI (traders dynamic index by Dean Malone) is based on RSI (13 period). A 34 period Bollinger Band is built in.

In volatile markets, the RSI will shoot out of the Bollinger Band and this is called a Sharkfin (looks like a sharkfin).

I built an EA which takes the data from the TDI (custom indicator). I am not able to "save" the time of a sharkfin and use it later.

For example: if the RSI shoots out to the upside of the bands (Sharkfin up) and some time later the same they shoots out to the downside of the bands (Sharkfin down) the EA should notificate me. I think this might be a little coding but I was not able to figure it out. I'm looking for a solution for about 4 months now.

Take a look on the picture and let me know if further information is needed.

I'd be very glad for your help.

Kind regards

Abi
