The vocabulary of order flow, market microstructure, and disciplined execution — explained in plain English for crypto spot traders. Educational content, not financial advice.
Absorption is when heavy selling (or buying) pressure hits the market but price refuses to move, because a large passive participant quietly takes the other side.
Accumulation is the patient building of a large position at low prices, executed quietly to avoid pushing the price up before the position is complete.
Backtesting evaluates a trading strategy by running its exact rules against historical market data and measuring what would have happened.
A basis point is one hundredth of one percent: 1 bp = 0.01%, and 100 bps = 1%.
The bid-ask spread is the gap between the highest price buyers currently offer (the bid) and the lowest price sellers currently accept (the ask).
A bull trap is a price move that looks like an upside breakout, draws buyers in, then reverses sharply — trapping late longs at the top.
Buy pressure is the aggregate force of participants trying to push price up — aggressive market buys plus firm resting bids; sell pressure is its mirror.
A dry run executes a trading system's full decision pipeline while suppressing the final step — no order is sent anywhere.
A kill switch is an emergency control that immediately halts all trading activity — cancelling open orders and blocking new ones — with a single action.
Liquidity is how easily an asset can be bought or sold in size without moving its price.
Live trading is trading with real funds on a real exchange account, where every order actually reaches the market and every mistake has a monetary cost.
A maker adds liquidity by placing an order that rests on the book waiting to be matched; a taker removes liquidity by sending an order that executes immediately against resting orders.
Market microstructure is the study of how trading actually happens: how orders become trades, how the order book and matching engine work, how spreads, depth, and fees shape prices at the smallest scale.
A market regime is the prevailing behavioural state of a market — trending or ranging, calm or volatile, risk-seeking or risk-averse.
Maximum Adverse Excursion is the deepest unrealized loss a trade experienced between entry and exit — the worst drawdown of that single position.
Maximum Favorable Excursion is the largest unrealized profit a trade reached between entry and exit — the best moment the position ever saw.
Momentum trading buys what is already moving up and sells what is already moving down, betting that recent strength persists over the near term.
Notional value is the full money size of a position: quantity multiplied by price.
The order book is the live list of all resting buy orders (bids) and sell orders (asks) for a trading pair, arranged by price.
Order book imbalance measures how lopsided the resting liquidity is between the bid side and the ask side of a market.
Order flow is the live stream of orders arriving at a market — who is buying and selling aggressively, in what size, against what resting liquidity.
Paper trading means executing a strategy with simulated money against real market prices.
PnL — profit and loss — is the money result of trading activity.
Slippage is the difference between the price you expected when you placed an order and the price at which it actually filled.
A stop loss is a pre-placed order that closes a position automatically when price moves against you to a defined level.
A take-profit is a pre-placed exit order that closes a position automatically once price reaches a target in your favor.
The taker buy/sell ratio compares aggressive buying with aggressive selling: the volume of trades initiated by buyers (takers lifting the ask) divided by the volume initiated by sellers (takers hitting the bid).
An edge is a repeatable reason why a strategy makes money after all costs — a statistical advantage that persists across enough trades to overcome fees, spread, slippage, and losing streaks.
A trailing stop is a stop order that follows the price as it moves in your favor.
A volume spike is a sudden jump in trading activity far above a market's normal level.
Win rate is the percentage of closed trades that ended in profit.
