Index
Short, neutral definitions of the words the guides use. Where a guide explains the mechanism in full, the term links to it.
The gap between a derivative's price and the spot price of the asset it tracks. On a perpetual, spot usually means the index price, and funding is what pulls the gap toward zero.
A prop firm rule that checks how evenly profit is spread, typically by asking how much of the total survives once the single best day is removed. Depending on the rulebook, falling short can hold progression rather than end the account.
Read the guide →A margin mode in which every open position draws on the same shared balance. It widens each position's buffer, but when a forced close does come, it can take more of the account with it.
Read the guide →The decline allowed in a day-based window, measured from a reference point the rulebook sets, such as the day's starting balance or the highest closed balance of the last 24 hours. Whether it resets at a fixed time or rolls depends on the rulebook.
Read the guide →A periodic payment between traders holding opposite sides of a perpetual contract, not a fee to the venue. When the perpetual trades above the index, longs pay shorts; below it, shorts pay longs.
Read the guide →The highest balance an account has ever reached. It only moves up, so a loss limit anchored to it gets stricter in absolute terms as the balance climbs.
Read the guide →A reference price combined from spot prices of the same asset on several external markets. You cannot trade it on the perp venue; it tells the venue what the asset is worth elsewhere.
Read the guide →A margin mode that limits a position's collateral to the margin you assign it, so a forced close can take that amount and no more.
Read the guide →The setting that decides how much of your own balance a position sets aside as margin. It adds no capital; it changes the buffer between your entry and a forced close.
Read the guide →An order that names the price: a ceiling for a buyer, a floor for a seller. It buys certainty of price and leaves the fill open.
Read the guide →The forced close of a position by the venue once equity falls to the maintenance margin, because the remaining equity can no longer absorb further losses.
The price at which a position's equity reaches the maintenance margin. Perp venues usually check it against the mark price, not the last trade.
The equity floor that keeps an open position alive. If equity falls to it, the venue closes the position.
Read the guide →A maker order adds a new price to the book and waits; a taker order matches a price already there and fills at once. The fee category follows that behavior, not your intent.
Read the guide →The price perp venues usually use to value open positions and check margin. It starts from the index, reflects where the perpetual trades, and is smoothed so a single trade cannot move it.
Read the guide →The total number of derivative contracts currently open on a market. It changes only when positions open or close, which makes it a stock, while volume is a flow.
Read the guide →A central limit order book holds resting buy and sell orders ranked by price and matches them by price-time priority. It does not set a price; it enforces the order in which orders fill.
Read the guide →A futures contract with no expiry date. Instead of a settlement date, a funding rate between longs and shorts keeps its price tied to spot.
Read the guide →A snapshot showing that assets sat at given addresses at one moment. Without a matching disclosure of liabilities, it cannot show solvency.
Read the guide →Compares the distance from your entry to the stop with the distance to the target. It describes the size of a win relative to a loss, not how often a plan wins.
The gap between the price you expected and the price your order filled at. Nobody charges it: liquidity, volatility and order size drive it, and it can work in your favor.
Read the guide →A conditional instruction that waits for price to reach a trigger level, then sends an order. A stop-market buys certainty of execution, a stop-limit certainty of price.
Read the guide →A state in which your decisions follow your last result instead of your plan. It usually starts with one trigger and builds through revenge trades and growing size.
Read the guide →The decline measured from the account's highest-ever balance. The reference point only moves upward, so your room tightens with every new high.
Read the guide →No term found. Try another word.
How a contract without an expiry date stays tied to spot, which of the prices on your screen actually judges your position, and what each order type costs you. Start here if you have traded spot and want the derivative side explained as mechanism, not jargon.
Leverage changes your buffer, not your capital. This path follows one position from the margin it ties up to the point where the venue closes it, then to the limits that measure your whole account.
What a funded account is under the marketing: who carries the risk at each stage, what the rules actually measure, and how to read an offer before and after you sign up. Every model in this path is explained as an industry category, provider-neutral.
The part no rulebook writes for you: recording what you actually did, catching the moment your decisions stop following your plan, and knowing what changes when software makes the decisions.
Trust gets replaced by things you can check yourself. What a reserves snapshot proves, how to read a chain without asking anyone, and what a verification layer is for.
Start with Path A, Perpetual futures mechanics. It opens with the overview of how perps work and then covers funding rates, mark and index price, open interest, order books, order types, fees and slippage. If you already know the derivative side, Path B follows one position from the margin it ties up to the point where the venue closes it, then to the limits that measure a whole account.
Path A starts with the mechanics, so you can begin there. The guides explain each term as a mechanism, and the term index defines the words they use. Path A is written for readers who have traded spot and want the derivative side explained. Path C explains how prop trading works as an industry category.
