That's good to hear, at least you're finding success/progress on SIM. I know of a place that would consider you if you could show several months of live trading stats. You would only need to have traded the minimum size to show your method in action and illustrate that you have the psychological strength to trade live.
I don't trade full time unfortunately but that's my goal eventually. Currently I work in a related field in finance and work varying shifts to cover the different shifts. This allows me time to trade the EU or US open sometimes which is good. The rest of the time I just read a lot, make notes and prep for potential trade opps. Once I've got a track record built up on live and I have some funds to support living expenses for 12 months I'll take some time out to try my hand full-time.
Can I ask what got you interested in spreads over outrights? Do you feel that spreads are less risky? I ask because even when spreading you have a position in the market (reversion to/from mean). Any books/threads you could recommend?
