Trading Smaller Caps
I have had my issues with IG in the past on smaller cap shares with their triggering of stops etc but i would recommend them as one of the largest and therefore ‘safest’ of the spread-betters. I hold between 50-100k GBP on account with them at the moment but would be uncomfortable with much more than that. If you have a credit account then you just have to prove that you have the assets and they will not require you to hold all your margin on account. However, if you get a margin call then you usually have to deposit the difference within the day or they start closing positions.
If you are a bigger player then you may prefer the services of the CFD part of IG. However, i like the tax free status of spread-betting and so stick with that. I had a CFD account in the past but it didn’t suit my style of trading.
