[Book cost - why it's changing?]

[CFD Margin Change]

Since IG decided to increase CFD margins to 100% on several stocks, I have the following question:

If I have enough funds in my account to cover 100% of my entry of positions, there should be no chance of getting margin called, or having my positions automatically closed, right?

[Can't find a specific stock...why?]

Total rookie question here. I'm trying to trade $EVSI, Envision Solar and can't seem to find it in the IG interface. With all of my searching, I can't find a reason why. Does anyone know why I might not be able to find it/trade it?

Thanks
