The [Glossary](/trada-docs/reference/glossary.md) carries the full list. ## Copier A **copier** connects one **sender** account to one or more **receiver** accounts, plus the shared rules that apply to them — working hours and symbol filters. When the sender opens, modifies, or closes a trade, the copier replicates that action to each receiver according to its own settings. A copier handles a single market type: a Forex copier contains only Forex/CFD accounts, and a Futures copier contains only Futures accounts. The two never mix within one copier. ## Sender The **sender** is the master account a copier copies *from*. Each copier has exactly one sender. Every trade on the sender triggers a copy operation to the receivers. ## Receiver A **receiver** is a follower account a copier copies *to*. A copier can have many receivers, and each carries its own independent settings: lot sizing, stop-loss and take-profit handling, and risk protection. The same account can be a receiver in several copiers, and an account can be a sender in one copier while being a receiver in another — but never both within the same copier. ## Partner account A **partner account** is an account held with a prop firm or broker in Trada's partner list. Partner accounts are exempt from plan account limits and may qualify you for [Free Starter](/trada-docs/plans-and-billing/free-starter.md). ## Working hours **Working hours** are a per-copier schedule that restricts when trades copy. You define one or more time blocks per day; outside them, no new trades are copied. Optionally, open positions can auto-close when a working-hours period ends. ## Protection **Protection** is a set of per-receiver thresholds and automated actions. You set Daily and Overall loss/profit limits (in % or $), and choose what happens when one is reached: send a notification, stop the copier, or flatten the account. See [Risk protection](/trada-docs/copy-trading/configure-receiver/risk-protection.md). ## Trading Health Score The **Trading Health Score** is a 0–100 composite that averages six normalised sub-scores: drawdown, profit factor, win rate, reward-to-risk, expectancy quality, and winning days. It summarises how a process is running, not what it returns. See [Trading Health Score](/trada-docs/reports-and-analytics/health-score.md). ## Related * [What is Trada](/trada-docs/getting-started/what-is-trada.md) * [How copy trading works](/trada-docs/copy-trading/copy-trading.md) * [Glossary](/trada-docs/reference/glossary.md) --- # Agent Instructions This documentation is published with GitBook.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter: ``` GET https://trada-llc.gitbook.io/trada-docs/getting-started/core-concepts.md?ask=&goal= ``` `ask` is the immediate question: it should be specific, self-contained, and written in natural language. `goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal. The response will contain a direct answer to the question and relevant excerpts and sources from the documentation. Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
