Introduction 

Consistency checks are done after transactions have been uploaded. You may do this to track down any errors and strange behaviors in your account. 

There are 3 types of checks - 

1) Contract Data -  To give Contract(s) with position which prices are not updated, for over 35 days.

2) Portfolio Data - To identify missing or strange behaviour of portfolio and NAV. This may indicate other upload issues such as incorrect ticker/prices, wrong transaction hash tags, etc.

3) Blotters Data - To highlight inconsistencies and/or (potential) errors of transactions. Checks can be run for transactions in a specific period when required.
