Thanks for that Eugene,

I had a chat with Vincent there, who is working with me on this. We just 
discussed the logic for comparing the next two contracts. Here's an example:

- JBT needs to know the correct contract for ES.
- It calls a new method getMostLiquidContract(ES, 4, 3, 3), where:

   - 1st parameter indicates the symbol,
   - the 2nd is the number of contracts in a year (4), 
   - and the 3rd is the first contract in a calendar year (3 (or March)).

- From there we can get the next two contracts: Sept and Dec, and it's 
abstract enough to use for all symbols.
- Once we're in Sept, it would start comparing the Dec and Mar (next year).

We'd never be trading a Sept contract in Sept right? It'll always have 
expired by then. Let us know what you think. Hoping to have the code ready 
for next week.

regards,

Michael.
