When it comes to doing scalping, it’s very much obvious that we all hate slippage/spikes, so that’s why we need to make sure we work with broker that don’t have such issues. I believe ECN is the best option for it and that’s why I go with OctaFX broker since they are a true ECN and have amazing set of conditions plus cTrader platform, it’s especially develop for ECN trading and allows me to work nicely which automatically leads into success.
