Thank you for contacting Fusion Markets.
MT4 is quite confusing in that what they call 20 points (such as setting a stop loss) is actually 2 pips. MT4 considers 10 points a pip.
Furthermore, CFDs like: Indices mostly work on a per point movement which is different to pips.
I hope this answers your question please feel free to contact us if you have more queries.
Have a great day and Happy Trading!
