Forex Brokers and slippages

Hi all,

I have a scalping system that trades the EURUSD but I am suffering from slippages because I try to capture fast movements AND I trade big sizes.

I am with an ECN broker (IC Markets), and when trading 10+ lots, I get slipped on average -0.9 pips PER TRADE which is simply unacceptable. It is already set up with one of the fastest VPS.

Anyone has any ideas how to solve this issue?

1. Trade with a market maker? Would fast execution and slippages be an issue here?
2. Diversify funds with other ECN brokers in hopes that they use different liquidity providers?
3. Any other ideas please?
