and mine.... What are `stale prices`?
Hi Encantador
Apologies for the delay in answering your question, I was in sunny Munich yesterday.
A price is derived from a blend of sources in the underlying market. We will take the middle of the best bids and offers, put our spread around it and publish that rate.
Our blend is lightning fast but like all pricing engines it relies on getting prices. We will set up each product with a different profile for pricing. For example in a product that is very liquid and has huge volumes of business such as EURUSD our pricing engine will receive lots of updates very frequently. We may set our EURUSD profile to alert us if there has not been an update for 15 seconds, the system will then default to putting that product on 'telelephone' only trading. Once we receive a price update then the system will automatically put the product back on to live online trading.
For the less liquid pairs for example the system may only search for a price update once every 2 minutes. These are the most likely occassions where we will be publishing a price online that has failed to keep up with price movements in the underlying market - this is what i consider to be a stale price.
Depending on the magnitude of the difference will determine the outcome between us and the client. But we've ALWAYS been fair, and we take most differences on the chin , but not the big ones.
Hope that helps
Best, Rob
