Exchanges 101 — Accounts, Fees, Security, Testnets
Spot vs perps, maker/taker and funding, cross/isolated margin and liquidations, 2FA/API safety, and testnet/paper trading. Understand the mechanics before placing a live trade.
2.1Spot vs Perpetual Futures; margin modes; leverage risk
Spot
- No funding; no liquidations
- Position size = cash available
- Fees: maker/taker
- Withdrawal fees apply
Perpetual Futures
- Leverage available
- Funding every N hours
- Liquidations possible
- Choose isolated or cross margin
Margin Modes
Isolated Margin
Risk is ring-fenced per position. Liquidation of one position does not drain full wallet.
Cross Margin
Wallet balance backs all positions. Liquidation risk spills over if size/leverage is high.
Typical: 0.4-0.5% for low leverage
Disclaimer: Illustrative only. Actual liquidation prices vary by exchange, position size, and market conditions. Always check your exchange's liquidation calculator.
2.2Fee tiers and short targets (calculator)
Maker (adds liquidity) vs Taker (removes). VIP tiers lower fees with volume. For short targets, fees can be a large % of TP.
Cost-to-Target Ratio
10.0%
Execution: Taker
Fee per side: 0.050%
Total fees (entry + exit): 0.100%
Target profit: 1.0%
2.3Funding rates (what, when they hurt)
What is funding? Perpetual futures use periodic payments between longs and shorts to keep the price near spot.
- Positive funding → longs pay shorts
- Negative funding → shorts pay longs
- Typical: every 8 hours, ~0.01% (can spike to ±0.1% in extreme conditions)
Mini Calculator: Holding Cost
Typical: 0.01% (can be negative)
Note: Funding rates change dynamically. Check your exchange's current rate before holding multi-day positions.
2.4Security best practices (2025-ready)
Safety Note: Never grant remote access to unknown parties; do not share API keys.
2.5Testnets/paper trading (practice first)
Many exchanges provide testnet or paper environments (e.g., Binance testnet, Bybit demo). Use them before live funds.
Practice Steps:
- 1
Create testnet/demo account (as available on chosen exchange)
- 2
Fund testnet wallet (faucet) or use paper balances
- 3
Place example OCO: TP/SL; test partial exits
- 4
Review filled/canceled orders and fee logs
2.6Practice: fee impact estimate for your target
- Choose your target TP % (e.g., 0.4–1.0%) and execution (maker/taker)
- Input fee % and (if perp) expected funding during hold into calculators
- Record Cost-to-Target % and decide 'OK/needs larger target'
2.7Exchange setup checklist (final deliverable)
Hint: Keep a screenshot of each setting for records.
