I use IG for my more serious trading and I am using SLM for trying out new strategy ideas and basically giving me something to do while waiting for my set ups. It stops me from over trading through boredom. I sometimes use this account to quench my thirst to gamble (so I just could not use a demo account for these purposes). The funny thing is that I have only ever had one loosing day on SLM. I find it very easy to profit with them. This could well be because I have no pressure on this account.
Would I load up £50k in the account? I don’t know. Maybe gradually over a long period of time, as confidence grew with them.
I am trading currencies and commodities with them.
I nearly always enter pending orders, so I always get the price I want. This also slows me down to make more thoughtful decisions. On the occasions I enter at market on 5/15m t/f if the market is moving fast I could sometimes get a re quote but not often. If this happens and I still want in, I just click for a 2pip max deviation on entry price, job done. If I ever do this it is because the market is moving fast in my direction so it is no skin of my nose, in fact I look at it as an indicator!
Good points- Quick loading of charts, quick loading of different chart templates, multiple accounts, can use record keeping stuff like myfxbook, lots of indicators freely available, Good place to practice with small size, Excellent range of FX, Very good spreads on exotics.
Bad points – Not enough commodities, money markets, ETF and indices are covered.
In summery – I really like them, slightly untested with size though. At the moment I think the largest size I have had with them is £2 a pip. If my confidence grows with them I may start using them for bigger and bigger sizes.
