I didn't find any information related to the availability of watch lists or scripts in Nest Trading Platform, but that doesn't mean they're not supported. I also didn't find a way to obtain the software to test it by myself. The only thing that remains is to test it by yourself. Go to Help to read about the features and software's capability.
Based on the previous experience, I know that most of the trading platforms are MetaTrader-based, therefore it's a big possibility that watch lists and scripts to be supported.
If I am right, use the following link to read how to create watchlists in MetaTrader: https://goo.gl/HkNBsS
