Eligible invited new users can get up to 20% of trading fees back. How much, which products, which regions, what conditions and for how long all depend on the Binance sign-up page at the time and on local rules — we relay, we do not underwrite.

Spot the traps · before you lose money learning

Know these traps first

01 / Most common

An order that won't fill

Not a stuck order — it's queue rules. Understand it before you cancel, and don't panic-chase the price into slippage.

 02

Slippage

Why a market order fills at a different price

 03

Order limits

Why min size/amount throws an error

 04

Modify / cancel

How to fix a misclick

 05

Read your average

How avg price / P&L are figured

06 · Leverage / futures risk

It magnifies losses, not your edge — master spot first. We urge you to be cautious.

Deep dive · matching rules

What happens between Confirm and a fill

From the moment you hit Confirm to a fill or a spot in the queue — what actually happens in between. We unpack the matching rules step by step, so "why didn't it fill?" never stumps you again.

Bought crypto but can't find it? Where it lands and whether you can sell right away
P2P buys land in Funding, not Spot, and need a transfer before you can sell. A short Spot balance usually means an order that hasn't finished. Trading isn't blocked; withdrawals can be.
Accounts 2026-09
Why your order gets rejected in a listing's first minutes
The allowed price range hangs off trades that have just happened — and on a new pair those are still being made. Same price, accepted then refused.
Safety 2026-09
Fat-fingered a limit price? Why it filled at once or got rejected
Typed 24,000 instead of 2,400? A little high fills straight away; far too high and the order never shows up.
Safety 2026-08
GTC, IOC and FOK — what time in force actually does to your order
It sets how long the order lives, not the price it gets. What happens to the unfilled part under IOC and FOK, and why a killed order logs as Expired.
Rules 2026-07
The 25% / 50% / 100% bar on Binance's order form — what it's actually a percentage of
It measures your available Spot balance, not your position. Buy side counts your quote currency, sell side counts your coin, with extra checks before using 100%.
Safety 2026-07
Binance partial fill: what it means and what to do with the rest
'Partially Filled 6/10' isn't a glitch — part filled, the rest is still in line. Whether to wait, cancel or modify, and how fees and average price are counted.

Leverage / futures: why we urge beginners to steer clear

Spot alone will keep you busy learning for a long time. Leverage and futures magnify losses, not your edge, and liquidation often comes faster than you'd expect. Master the spot rules and know how much you can afford to lose before you go anywhere near them. Read the risk note →
