Using sym for notifications and predictions

As a follow-up on the sym workflow posted earlier,  here are some uses for sym.

Notification applications

The following will apply to any kind of notify-on-change kind of apps:

1. Create sym check the price of gold continuously called say, goldpx. 
1. Link goldpx to diffcheck
2. Get sms notifications whenever the price of gold changes

Prediction applications

This is quite rough but does seem doable.

1. Create a sym that's a neural network called say, nn, 
• Set nn mode to train
• Link goldpx to nn for a day or so. 
• Set nn mode to predict 
• Link nn to diffcheck
• Get sms notifications whenever the neural network a change in the price of gold
