OANDA Forex Order Book - good or bad?

Hello,
Just found out that OANDA has something called Forex Order Book. What is it and can it be an asset in trading decisions? If yes, then how to interpret the data received? The more sellers(asking) than buyers = bearish? The more buyers(bidders) than sellers = bullish?
Any light regarding this would be appreciated.

Cheers!

It's a bunch of BS, just like volume in the Forex market is BS, and many other things, such as the COT report, Fibonacci, Harmonic Patterns, Crossing Moving Averages, Elliot Waves, etc... This stuff doesn't work. And if it does appear to work, it's mere coincidence. If only trading were that easy!

I'll still look for information about it, but in fact I think it's just another analytical collection that helps in decision-making, but I would probably not use it as a direct guide to action, as well as signals - it can all be a guide, I'm against a trader blindly relying on some data - without analysis, without a critical understanding of the situation. Here it is very important to use several sources of information in order to make the most specific action plan. But anyway, I will repeat once again - do not rely on it as the only correct source of information. The market is volatile and complex, so you have to be as careful as possible.
