I don't agree with the comments about sharing EA, especially after looking at level 2 data. If everyone keeps the same settings, runs it on the same currency pair, and the signals all agree, then I can see there being some sort of issue.

Brokers interpret the level 2 data in so many different ways to feed as quotes, I don't think there is an issue. Also with known SL/TP numbers visible at the dealing desk, some brokers will cash out trades while others won't by intentionally hitting SL or intentionally missing TP.

Brokers are unlikely to trade something under 5 lots, and if they do it is because their aggregate doesn't cancel out. If that boker has 200 lots BUY EURUSD and 150 lots SELL EURUSD they may want to BUY 50 lots. Hitting SL/TP numbers reduces their risk drastically.

I am liking the idea of manual closing more and more, but it appears you need a datacenter for this to actually be a good idea. Also, some TP/SL should be set 'just in case' but the datacenter will be on 24/7. I'm looking at sharing some OC-48 datacenter space with other people, is anyone interested? (For EA Hosting)
