Cant place trades on US500 - mt4. And indicies Lot sizes

Recently I decided to add US500 to my watchlist but when I try to place an order on my MT4 It’s not letting me (Screenshot).
Also how do lot sizes differ from forex pairs and indicies? I noticed when I calculate the loz sizes for indices it’s not the same as with forex.

.

Thank you in advance.

Yeah lot sizes for indices are 1 I believe which means you don’t have enough money to open a position. I believe MT4 has a section where you can check the contract specification to see lot size / margin info!

Hmmm. :thinking: This is a response to a similar question so it might be of some help! :smiley:

Just email your broker and ask. Start with the Minimum lot size available.
