Slippage is nothing new with these brokers like IC Markets or any of those small deposits-huge leverage brokers because they are NOT real ECN brokers. They claim they are STP, DMA, agency-model, ECN or any of those terms but in reality they are still MM brokers in disguise. They stand in between you and the "liquidity providers" and don't really send your orders directly to the "liquidity providers" to be executed. I don't know exactly how they operate but I suspect that when you put in an order, you are actually trading on some sort of internal "ECN" of the broker NOT really the interbank market comprised of those "liquidity providers" with all those shiny logos that scroll across the bottom of their webpage like Citi, UBS, Deutsche (It's just NOT possible that Deutsche would be executing our 1K microlot orders no matter how much we wish for it LOL) like what they impression on you and then they turn around and hedge your trades with the "liquidity providers" so your order is executed on the interbank market "in a way" but through them and they earn a spread between the price that they filled your order and the price that they got their hedging order executed by the "liquidity provider" hence the slippage. So they are basically Oanda or FXCM in a different form. Nothing wrong with being Oanda or FXCM really because many traders trade with MM type brokers and are quite happy with them BUT they should make their true nature known instead of hiding behind the brand of "ECN", "STP", "DMA" when they are really market makers so the traders who really want to trade on TRUE ECN type brokers don't waste their time with them. And this is especially true if you trade CFD's on oil, gold and indexes when they even state that they are the issuer and hence the market makers of those instruments UNLESS you trade the REAL ones on the exchanges like the ASIX.

If you want virtually no slippage and even positive slippages many of the times, I would suggest you look to trade with more purer ECN brokers like Interactive Brokers, LMAX, LCG and etc. Despite Interactive Broker's horrible in-house trading platform and bad charting software, its execution is very decent, super fast and very little slippages. The rest of the brokers' actually offer better platforms like HotSpotFX and etc. but their min. deposit is quite steep. There is actually a very easy way to test whether a broker is a true ECN broker or not is that you post a limit order in between the bid-ask spread and if you actually see your order showing up on the quote screen and actually narrowing the spread then you know you are dealing with a true ECN because that means your order is visible to all and can actually be executed against. In other words, you have actually become a liquidity provider yourself. True ECN brokers would allow you to become liquidity providers and brokers like MB Trading even let you earn commissions if you provide liquidity to the market. But if you never see your limit order showing up there then you know you are dealing with an Oanda. My order ALWAYS showed up in the quote screen on their albeit horrible TWS.

But all those pure ECN brokers require much higher minimum deposit with at least 10K like in Interactive Broker's case which makes sense. If you want to participate in the "interbank" market directly against banks like Deutsche, a company that has $Trillion of assets, how are you going to do it with just microlots and $500 deposit even with high leverage.
