01 · Spot Trading Basics
Spot is the most primitive and simplest form of trading: cash for goods, hand to hand. You pay and immediately receive the underlying asset itself (stocks, coins, commodities) — no shares to return, no expiry date, no forced liquidation. This article walks through the complete logic of spot trading, from definition to order placement, fees, and even how to "short spot indirectly".
1. What Is Spot
Spot is a way of trading in which both parties exchange cash for goods and transfer ownership of the physical/financial asset immediately (or within a very short time). Once you buy, the asset truly belongs to you — you can hold it for 1 second or 10 years, with no forced deadlines of any kind.
Compare it with the spot deals most familiar to you:
| Spot instrument | What you actually buy | Common venues |
|---|---|---|
| Spot gold | Gold bars / paper gold | Banks, gold shops |
| Spot forex | Foreign currency cash or account balances | Bank counters |
| Stock spot | Company shares (T+1 settlement) | Stock exchanges |
| Crypto spot | The coins themselves (on-chain or exchange balances) | Exchanges: CEX/DEX |
| Commodity spot | Physical soybeans, crude oil | Spot wholesale markets |
Key Characteristics of Spot
- Real transfer of ownership: once bought, the asset is yours — you owe nobody anything.
- No leverage: 1 dollar buys only 1 dollar's worth of goods; your maximum loss is your principal.
- No expiry date: there is no "delivery day" — you decide.
- No forced liquidation: however far the price falls, you can never be "liquidated"; at worst you carry an unrealized loss.
- Sources of return: the spread from buying low and selling high + income generated while holding (dividends, interest, staking, etc.).
Spot Is the Foundation of All Other Trading
Futures, perpetuals, options, and arbitrage are all essentially derivative games played around the "spot price". Only by understanding spot can you understand why, in derivatives, "some people are willing to pay a premium" and "some people need to hedge".
2. Spot vs Futures: One Table Says It All
| Dimension | Spot | Futures |
|---|---|---|
| What is traded | The underlying asset itself | Contracts for future delivery |
| Leverage | None (full payment) | Yes (margin system, typically 5-20x) |
| Delivery | Instant settlement, instant transfer of ownership | Fixed delivery date (or daily/periodic settlement) |
| Shorting | Cannot short directly; indirect means such as securities lending needed | Open a short position directly |
| Holding period | Unlimited | Must close or roll before expiry |
| Liquidation/forced liquidation | None | Margin shortfall triggers forced liquidation; the entire principal can be lost |
| Risk level | Maximum loss = purchase cost | Theoretical loss can exceed principal (negative balance) |
| Capital tied up | Full amount | Only the margin (leverage amplifies both return and risk) |
| Typical instruments | Stocks, crypto spot, paper gold | Index futures, commodity futures, crypto perpetuals |
One-line summary: spot is "buying groceries", futures is "signing an order". With groceries, the money is spent on the spot and what you buy is yours forever; with an order you only pay a deposit, price moves are settled on the full contract value, and if the direction is wrong the deposit is wiped out — and you may even owe more.
🛒 Spot groceries vs futures orders: one comparison decides everything
Spot is "buying groceries", futures is "signing an order" — with groceries, the money is spent on the spot and what you buy is yours forever; with an order you only pay a deposit, price moves are settled on the full contract value, and if the direction is wrong the deposit is wiped out and you may even owe more. For beginners, starting with spot essentially means starting from "owning an asset", not from "betting on contracts".
3. The Complete Spot Buy/Sell Flow (Exchange Example)
The following uses a typical centralized exchange (crypto CEX) as the example; the flow at stock brokerages is nearly identical, with only an extra "bank-broker transfer" step.
Complete Flowchart
Register / identity verification → deposit / fund the account → transfer to the spot account
→ place an order (limit / market / stop-loss / take-profit)
→ matching and execution → assets credited (position / available)
→ sell / withdraw → funds out to the bank cardStep 1: Registration and Identity Verification
- Choose a compliant exchange/broker and register an account.
- Complete identity verification (KYC) as required by the platform — usually an ID document and facial recognition.
- Crypto note: some platforms are region-restricted; using a VPN with non-real-name operation is a violation of the rules and leaves your funds completely unprotected. See 03-Crypto Spot.
Step 2: Funding
| Instrument | Funding method | Arrival time |
|---|---|---|
| A-shares | Bank-broker transfer (trading days only, 9:00-16:00) | Instant |
| HK/US stocks | Bank wire / broker-linked card deposit | 1-3 business days |
| Crypto CEX | Fiat purchase (OTC) / on-chain deposit | Minutes (on-chain requires confirmations) |
⚠️ Funding does only two things: verify the channel works and verify the funds are yours. Before any large deposit, run a small test transfer and confirm it arrives before scaling up.
Step 3: Order Placement and Execution
- Open the trading page and pick the trading pair (e.g. BTC/USDT, AAPL).
- Choose the order type (limit / market, see the next section).
- Enter price and quantity; check the estimated cost of "fill price + fees".
- Click buy; the order enters the matching engine.
- A limit order rests on the order book waiting for a counterparty; a market order fills immediately at the opposing side's price.
- Once filled, the asset enters your "positions"; unfilled limit orders stay in "open orders" (you can cancel them manually).
Step 4: Selling and Withdrawal
- Selling mirrors buying; the cash proceeds go into your "available balance".
- Withdraw to your bank card (in crypto: cash out to fiat or withdraw coins to an on-chain wallet); watch the fees and withdrawal limits.
Common Terms Quick Reference
| Term | Meaning |
|---|---|
| Best bid / best ask | Highest bid price / lowest ask price on the order book |
| Fill price | The price at which the order actually matched |
| Open order / cancel | An unfilled limit order / canceling that order |
| Depth | Order volume resting on the book; the thicker the depth, the harder the price is to push through |
| Slippage | The gap between the actual fill price and the expected price (obvious for large orders or low liquidity) |
4. The Four Order Types
| Order type | Meaning | Execution logic | Use case | Drawback |
|---|---|---|---|---|
| Limit order | Buy/sell at a specified price | Fills only when price reaches your specified level | Entering/exiting at a clear price; resting orders to catch pullbacks | May never fill |
| Market order | Fill immediately at the current best opposing price | Fills in seconds | Racing the clock (news moves, breakout moments) | Slippage; large orders may get a poor price |
| Stop-loss order (Stop) | Sell at market once price breaks below/above the trigger | Executes at market immediately after trigger | Controlling losses, avoiding deep traps | It is a market order after the trigger; the fill can be far worse in extreme moves |
| Take-profit order (Take Profit) | Sell once price reaches the target | Auto-fills at the target | Locking in profit, quitting while ahead | May sell too early and miss a further rally |
Combined Usage Example
Buy: limit order resting at 100
Downside protection: stop-loss trigger at 90 (loss capped at 10%)
Target: take-profit trigger at 130 (profit locked at 30%)- Stop-loss/take-profit is the only automated risk control in spot, ideal for those who cannot watch the market.
- Advanced usage: trailing stop — as price rises, the stop price moves up with it, locking in against drawdown.
- Some platforms support binding a "stop-loss + take-profit order pair" to the same position; whichever side is hit, the position is closed automatically.
⚠️ Risk Warning: a stop-loss order does not guarantee the fill price. In a flash crash, trading halt, or liquidity drought, the market order triggered afterward may fill far below the trigger price (slippage can exceed 10%). A stop-loss is "a tool to cap the maximum loss", not "insurance against losing".
5. The Fee Structure of Spot Trading
1. Trading Fees (Commission)
| Type | Typical rate | Notes |
|---|---|---|
| Maker fee | 0.02%-0.1% | You rest a limit order and provide liquidity; cheaper on most platforms |
| Taker fee | 0.05%-0.15% | You take existing orders off the book; more expensive on most platforms |
| Brokerage commission | About 0.025% for A-shares; a few dollars per trade for HK/US stocks | Varies widely by market; watch for minimum fees |
Crypto platforms usually charge "trade value × fee rate" directly; brokerages also levy stamp duty, transfer fees, etc. (A-share stamp duty is 0.05% on sells).
2. Other Costs
| Cost | When it occurs | Rough standard |
|---|---|---|
| Withdrawal / cash-out fee | Withdrawing to a bank card or withdrawing coins | Crypto charged by on-chain Gas; bank wire tens of CNY per transfer |
| Deposit fee | Fiat funding | Mostly free; wires incur intermediary bank fees |
| Funding fee (perpetuals) | Not in spot; perpetuals only | Does not exist in spot |
| Spread | An implicit cost on every trade | The gap between bid and ask; wide for thin books |
3. How Fees Eat Returns
- High-frequency trading is the hardest hit by fees: in-and-out all day at 0.1% per side can consume more than 10% of your principal in a year.
- The formula for true cost:
True cost per trade ≈ spread + fees + amortized withdrawal fee- Strategically: the higher your trade frequency, the more you need a low-fee platform, more resting limit orders (Maker rate is lower), and VIP/VIP0 discounts.
6. Indirect Ways to Short Spot
Spot has no native "short" button — without holding the asset, you cannot sell it. But the following methods achieve "profit when price falls":
1. Securities Lending (Borrow and Sell)
- Mechanism: borrow the asset from a broker/platform, sell it, buy it back cheaper later to return it, and keep the difference.
- Cost: borrowing interest (a few to tens of percent annualized) + trading fees.
- Risk: if the price rises, losses are theoretically unlimited, and the broker may force you to buy back (a short squeeze).
- Barrier: A-shares require margin trading permission (500,000 CNY threshold + margin exam); borrowing in HK/US stocks and crypto is more relaxed.
2. Buying Puts / Selling Calls
- Mechanism: buy a put option — the more the underlying falls, the more you earn; maximum loss = the premium.
- Advantage: loss is capped (only the premium), and no borrowing is needed.
- Drawback: time value decays; even if the underlying does not fall, the premium bleeds away.
- Fit: those worried about a short-term drop who want to hedge position risk.
3. Inverse ETFs (Overseas Markets)
- HK/US markets have inverse ETFs (e.g.
SQQQ, which shorts the Nasdaq index); buying it equals shorting the index. - Note: inverse ETFs suffer daily compounding decay — only suitable for short-term holding; long holding is guaranteed to underperform the theoretical value.
4. Shorting Futures (Strictly Speaking, Not Spot)
- Opening a short directly in the futures/perpetual market is derivatives territory, with leverage and forced-liquidation risk combined — not recommended as a shorting tool for spot traders. See 03-Futures.
| Method | Maximum loss | Barrier | Cost | Fit |
|---|---|---|---|---|
| Securities lending | Theoretically unlimited | High (margin account, 500,000 CNY threshold) | Borrowing interest | Professional investors |
| Put options | Limited to premium | Medium | Premium + time decay | Holders with hedging needs |
| Inverse ETF | Limited to principal | Low | Compounding decay | Short-term bears |
| Shorting futures | Can exceed principal (liquidation) | Low | Fees + funding | High risk tolerance (use with caution) |
⚠️ Risk Warning: the number one source of losses for spot investors is "opening futures just to short". Shorting inherently carries leverage thinking (borrowed shares, premiums, inverse products); once the direction is wrong, losses accumulate far faster than a spot buy. Do not attempt any shorting before you fully understand the margin mechanism.
⚠️ Risk Warning
⚠️ Although spot trading is the lowest-risk form, the following risks remain:
- Asset going to zero risk: a listed company delisted, a coin's team absconding, commodities spoiling — the price can hit zero and the principal is lost entirely.
- Platform risk: an exchange/broker going bankrupt, absconding, being hacked, or maliciously freezing accounts (especially unregulated offshore platforms).
- Liquidity risk: small-cap instruments have thin depth; a large sell order can crash the price or even fail to find a buyer.
- Operational risk: mistapping a market order, forgetting to set a stop, leaking passwords, entering a wrong address.
- FX and funding risk: when investing across markets, currency swings and frozen deposits can erode all returns.
Spot does not amplify risk, but it never eliminates it. Before buying any asset, assess first: would losing 100% of this money affect my life?
