CFD Slippage per contract

Gap (“gapping” or “slippage”)
Where a market moves directly from one correctly
quoted price to another, significantly different,
correctly quoted price or from one reasonably quoted
price by LCG to another reasonably quoted price by
LCG in relation to the size required by a client for
execution of an order. There can be many reasons for
gapping; economic figures, company announcements,
political events, natural disaster etc., but the effect is
that any fill on a stop-loss, limit or new order may be
subject to a ‘gap’ in the fill price from that requested
by the client in his/her order contract note.
