Latency Arb: Profitable settings?

[Lisa_Kelly]

Hey,

I understand how latency arb works in theory and I have been trying to get the 'right' settings all last week.

However, I have hit a brick wall.
Hence the reason I am here.
Image attached is my current settings for the EURUSD.

I am using cTrader - a VPS in London and LMAX data feed.

Any help would be most appriciated.
Lisa.
