The Black Knight who blogs here on Babypips gave some education on this issue of MT4 and the trustworthiness of brokers a while ago on his website forum. I hope this isn’t breaking a forum rule or something that I have pasted it in full here for information:

While we’re on the subject, I thought I would post a few words on the dealing desk (market maker) vs. ECN (electronic computer network) debate, as questions about this come up fairly often.
Market makers are not inherently “bad” - just the dishonest ones who hunt stops and trade against their clients. A market maker’s job is actually to try and match orders in-house first (if one of their clients is selling and another buying, for example), which leads to faster fills and lower spreads. The honest ones to not trade against their clients, they let clients trade against one another, then offset the difference to their own liquidity provider.
I’ve seen what trades look like from the broker’s side, and it is extremely difficult to zero in and trade against one user specifically. Think of a grid like an Excel spreadsheet with hundreds of rows and tiny little cells, where the numbers change in each cell second by second. No charts.
With ECN brokers, there tend to be variable spreads, wider spreads, and slippage - which reflects the true nature of the markets, since there is no “buffer” in the middle (after all markets invented market makers for a reason). But, certainly, it is much harder for an ECN broker to interfere with accounts (since everything is automated), so perhaps the higher price is worth paying.
If you require the MetaTrader platform, you will find that everyone who uses it is a market marker (it was designed for market makers). Crown Forex and FXCM are currently in the process of trying to adapt it for ECN use, though as we’ve seen both have encountered issues and delays. We have several people who use Crown, FxPro, and FXDD (myself included for the first two), and despite their being market makers there have been NO reports of irregularities thus far. In fact, strangely enough, when slippage occurs with FxPro it tends to favor the client.
If you do not require MT4, then our recommendation would be for FXCM UK or FXCM - they are a true ECN broker with multiple liquidity providers, geared primarily at institutional traders with demanding needs, and a solid firm with thousands of accounts, a reputation spanning years, and strong financials (they bought out Refco and several other failures in order to save client accounts, and even withstood the death of Lehman, who was a majority shareholder). And, you can always switch to MT4 later, if you like, when they’ve finished adapting it. Advanced users (who use us as their IB) can switch already. FXCM UK is who I trade my client accounts through, because there have slightly stricter client protection regulations in the UK than in the US.
