On the FXCM website it seems the live EUR/USD spreads throughout the day are around 0.1-0.3 or so. (during high liquidity)

Using OANDA I am getting the correct ~1.3-1.5 spreads to display in my algorithm. I wanted to know what what effect these low FXCM spreads would have on my strategy, so I switched to the FXCM data and brokerage model. However, from my math the spreads over the day look to be ~2.1 ? Is this to be expected? Or is it me who is doing something wrong?

Thank you for any information!
