Why does the note have to be valid JSON?

TrendSpider sends the note as application/json only when it is valid JSON.

Does a sell alert open a short?

That depends on the strategy's trading behavior, which sets how exits pair with entries.

Can I set the size in the alert?

Leave it out. Your Nyria bot sizes every order from its own settings.

Where do I see what Nyria read?

On the strategy's Logs tab, which shows each alert and how it was read.

Guide

How do I set buy or sell in a TrendSpider alert for Nyria?

TrendSpider has no variable for the trade direction or the quantity, so you type them in. Write buy as the action in the note of an entry alert and sell as the action in the note of an exit alert. Leave quantity out and your Nyria bot sizes the order. TrendSpider fills in the symbol and last price when the alert fires.
