Learn about CSRF
I don't see how using a "challenge token" adds any kind of prevention: what value should be compared to what?

Update using multiple JOINs in MySQL/Python
The first set of questions were deemed too similar to another post (it wasn't) and were closed... so I've made another attempt here, hopefully better worded this time. Some background: We have a relationship here. Securities (coins) + currencies (base coins) form a pair. A pair and a broker form an asset (I treat each broker/pair as a specific asset) and I also have a forex table that stores live currency rates. In my transaction history table (history_price), there is a column that contains a lot of NULL (Euro volume), and I do calculations based on the volume. What I want to do is fill it,
