The main reason behind including the broker name is for a few reasons:
- With several broker feeds (bucket shops too) we can calculate an average price between brokers and further figure out what happens when a broker moves away from the norm (does the price retrace?)
- We can detect broker spikes, record them, and see which brokers 'cheat'
If you can find a universally agreeable way to abbreviate the broker name I'll go ahead. I'm not sure how you're handling the .csv files, but I would imagine a simple "Find and replace" should be sufficient.
