Most brokers use the bid prices as the feed, correct?

Brokers like FXCM, ODL, etc etc.

I know Oanda uses a combination of Ask/Bid to show the feed on the candlestick chart but I'm just checking what other brokers do.

with fxsolutions and accucharts you can select the bid or the ask price for your charting. Doesn't really have much impact with them since their spreads are fixed.
