Audit of Sentiment Indicators of Banks / Brokers etc.

How can we be sure if a sentiment given by a Market Maker is true or intentionally false?
For example looking at fxssi web site and seeing that some brokers's sentiment is almost opposite. How do you explain this?


I really would like to know if any broker/bank has regulations / control for publishing of positions of its customers.

Thanks in advance.

I don't think it has any importance for a brokerage company, every client can trade as he likes, and much depends on the choice of strategy, timeframe, etc. And to keep such records for each client is just unprofitable in terms of time and financial costs, your time will just go to nowhere. For banks, this may be more important, especially given that banks are also market participants, and the largest. Perhaps they are analyzing the positions of their largest and most successful clients so that they can also participate in the market based on their performance. This definitely makes sense. But I don't think they will ever state it openly, because it is the application of client data for their purposes - which is probably not quite legal or at least not ethical.
