Retrieve current spread charge with API?

[wilsonK]

How do I get the spread charge of an instrument with the REST/Streaming API? For example, I can see US 500 has a 1.5 spread charge right now in the web platform, but I can't seem to find the API for it.

Spreads on IG are not fixed, they're dynamic. If you want to get the spread right now, you can sample the prices using either API, and work it out for yourself. But, of course, the value may change at any time after that

Hi, I think you misunderstood the question. I am not try to get the spread, what I wanted is the spread charges.

i.e. the extra spread IG put on top of the market spread when you open a position.

No, I understood fine. I think perhaps you minunderstand how spread betting works. The spread is the charge, hence the name.

It's not important anyway, the point is there no direct way to get the spread value from the API. You have to sample the bid and ask prices, and work it out yourself. The spread is dynamic, it changes according to market conditions, eg volatility. In my application I sample prices hourly using the Stream API, and calculate an average
