[Resolved]  Olymp Trade — Yo, where are multipliers

I've been trading on the market for a rather long period, but still can't get used quickly to the new environment whenever I step on the new platform.
Olymp trade was surprisingly a pretty straightforward broker for me from the point of the platform's functionality. I never imagined that there are such brokers which proprietary software can work so fast without any glitches, and with an intuitive interface.
Still, I faced some difficulties sorting things out how to apply leverage to the position. I heard guys talked about multipliers or multiplicators, whatever, but where to find them? I'm still on the demo and this is the only thing I can't understand.
Olymp trade guys should certainly create a separate video manual how to use these multiplicators as it's not really clear. But other features are cool and understandable!
