Every price you see is the last agreement between a buyer and a seller. Markets are a continuous auction: buyers post bids below, sellers post offers above, and price moves when one side gets impatient — a market buy lifts the offer and price ticks up; a market sell hits the bid and price ticks down.
This is why price doesn't glide — it JUMPS. When aggressive buying eats through all the sell orders at one level, price snaps to the next level where sellers are waiting. Big moves happen where orders are thin; price stalls where orders are thick. Traders call the thick zones liquidity.
What this means for you
- Price moving fast = orders are thin there. Expect follow-through OR a violent snap-back — not calm.
- Price stalling at a level = real orders are defending it. That's information (see Support & Resistance).
- News doesn't move price. The ORDERS that people place because of news move price. Sometimes they front-run it, sometimes they fade it.
Rule of thumb: ask 'who is trapped?' The side that entered late and is now losing must eventually exit — and their exits fuel the move against them.
In the Sim Challenge you're trading BTC's real auction. The entry, target and stop levels turn that continuous auction into a defined contest — but everything you learn reading the tape here is the same skill real traders use.
