So far i've only traded some on plus500.
Here are my questions:
I don't really understand how things work in the background. I've understood that the ask price is the best sell offer available, the best one determines the ask price right? So let's say someone is selling 1000 of something for the best price which is 900 dollars each, now I decide to sell only 10 of the same thing for 899, a better price, now is that going to change the ask price to 899? Doesn't really make sense because I'm only selling 10.
Ok here is a line of eur/usd tickdata output from dukascopy:
Local time,Ask,Bid,AskVolume,BidVolume
01.01.2010 00:00:21.820,1.43228,1.43218,1.5000,2.3000
So ask is 1.43228 and ask volume is 1.5000, does that mean 1.5000 of that thing were offered for 1.43228, or was it actually sold?
How much is 1.5000? How am I supposed to know if it's thousands or millions.
