Hello,

I am somewhat confused about Oanda's Core Pricing and live data feeds.

For example using QC's historical data, at 6/15/2022 00:00, the closing price on EURUSD is 1.04348 with bid/ask prices at 1.04339/1.04357. Suppose that we purchased $1 worth of this pair (ignoring slippage), then we now own 0.95824 EUR and have “paid” a spread of 0.9 pips.

With Oanda's Core Pricing, they offer a reduced spread and let's suppose that it is 0.4 pips. This mentions that “the spread is built into the price of the trade”. Does this imply that the live data feeds themselves are different depending on whether the account is set to Standard vs Core Pricing, or that the prices are the same but any market orders are automatically filled at more favorable prices (e.g. 1.04352 in the example above)?
