Alot of pro traders trade with oanda. But no pro scalper i know would ever trade with oanda. So it depends on your style. Alot of complaints about slippage and all would mainly come from scalpers. I remember a few years back scalping with oanda, i had slippage issues as well, 3-5 pips high slippage on 500k units, so it was fairly significant. But also I had machine running for 6 hrs with whole bunch of moving avgs and their java platform tends to slow the machine down after a while, atleast in my experience, so i'd have to always monitor that and clear my cache else I would have lag issues. So for scalping where you are going for 2 or 3 pips or whatever, its better to go with CNX or other ecn type or institutional platforms, and nowadays with many you can negotiate less than half of what the posted minimum requirements are for these accounts.
But really for regular trades, i find oanda to be pretty reliable and slippage not really an issue and i've been with them since 04 and have several 6 fig accounts with em.
