Quantity need must be equal or lower than 0 while trying to buy stocks

Hello, Suule.
It is a question which has popped up frequently, you can find an answer here:

“the maximum remaining quantity for long positions with this instrument is 0”

We have discussed this within other threads, but I will reply here as well - the maximum trading quantities of all CFD instruments are dynamic and reflect our current market risk evaluation. As a regulated company, we have to be in tune with the regulatory requirements for capital adequacy and market exposure.
