Create Copy · Parameters

Confirm the lead trader, execution mode, and account before creation. This page explains key parameters; specific numerical boundaries, account quotas, and pre-flight results are governed by the live page and server responses.

The New Copy page consists of three steps: 01 Select Signal → 02 Configure Copy → 03 Review & Launch. On the right, a persistent summary card titled "Review Before Launch" reflects your input in real time. This page follows these three steps to explain each parameter.

Workflow Overview

Step	What You Do	What the System Does
01 Select Signal	Paste Binance trader profile link or ID, or click "Follow" from a report	Validates trader identity, position visibility, and report freshness
02 Configure Copy	Select execution mode & account; enter capital and risk controls	Reads available capital ceiling; validates parameter ranges
03 Review & Launch	Click "Check & Review Launch Parameters", read pre-flight output, confirm	Server reviews configuration and returns copy ratio, projected positions, and warnings

You can freely move back and forth between steps. Modifying any parameter clears existing pre-flight results, requiring a fresh pre-flight check to prevent launching an outdated configuration.

Drafts persist in the current browser session (up to 24 hours), so leaving to bind an API Key and returning preserves your selected signal and parameters.

Signal, Mode & Execution Account

Field	Meaning & Checkpoints
Lead Trader / Signal	Verify target identity and report to avoid following the wrong trader.
Paper / Live	Paper routes no real orders; Live places orders on the exchange based on signals.
Execution API Key	Live mode requires selecting a verified, bound account; Paper does not.
Task Name	Used to identify tasks; does not alter any execution rules.

Lead Trader / Signal

• You can paste a trader profile URL (containing portfolioId= or /lead-details/) or enter the ID directly.
• After filling, click "Check Trader". The page displays the name, venue, ID, and "Positions Visible / Positions Hidden" badge.
• Traders with hidden positions cannot be copied. The platform strictly prevents task creation. This is a non-negotiable rule.
• Submitting pre-flight triggers a second verification of identity and position visibility; if results diverge, the latest check governs.
• To inspect underlying performance first, click "View Trader Report".

Paper / Live Mode

Mode	Places Real Orders?	Requires API Key?	Best For
Paper · No exchange orders	No	No	Validating parameters, checking signal frequency
Live · Automated execution	Yes	Yes, and verification must be valid	Confirmed strategy and clear risk tolerance

Two points often overlooked:

• In Live mode, if your account lacks live copy privileges, the interface automatically reverts to Paper mode and clears capital. This is an intentional safeguard.
• Paper tasks also consume "Allocated Capital" quota according to your subscription plan.

Execution API Key

• The dropdown lists only bound keys, tagged as "Verified" or "Check Permissions".
• Upon selection, the system attempts to read the account's currently available capital, showing "Max Available Capital: N USDT".
• If reading fails, do not guess; click "Re-read". Pre-flight will be blocked if balance cannot be determined.
• A key can only run one live task at a time; selecting an active key will trigger an error: "This key already has a live copy task running".

Task Name

An organizational label up to 128 characters. It has no effect on trading rules. We recommend naming by "Trader + Mode + Capital" (e.g. sonar-ETH-live-500) for easy identification across multiple tasks.

Capital, Positions & Leverage

Field	Meaning & Checkpoints
Capital Limit / Allocated Capital (USDT)	Baseline figure for position sizing; not actual margin locked. Max available capital is determined by the server from balance and quotas, and can only be adjusted downward. Re-read if loading fails.
Single-Coin Max Position (USDT)	Caps position size for any individual symbol; must be evaluated alongside capital and leverage.
Risk Multiplier	Multiplies the ratio of the trader's position to their equity; not a profit multiplier.
Leverage Mode / Fixed Leverage	Follow lead trader or set a fixed integer; only enter a value when fixed mode is chosen. Subject to exchange caps.
Max Notional Exposure (if shown)	Constrains total notional position size; distinct from capital and margin.

Allocated Capital

The most commonly misunderstood field. Remember three truths:

1. It is capacity, not locked margin. Entering 500 USDT does not mean 500 USDT is immediately placed into margin.
2. It has a ceiling and can only be reduced. The effective ceiling is the lesser of "server-returned max available capital" and "remaining plan quota". Entering more will prompt "Max allocatable is N USDT".
3. It is not your maximum loss. Loss depends on position sizes, leverage, slippage, and market moves, and can exceed this number.

Formatting rules: must be > 0, up to 2 decimal places. Paused or abnormal tasks continue to occupy quota; only stopped tasks release quota.

Effective Capital

During live task execution, if account equity falls below the configured capital, the system operates with lower effective capital (a notice appears: "Account balance is below configured capital N USDT; currently operating at M USDT"). In this state, risk limits and drawdowns evaluate against effective capital, not your initial configuration.

When configured capital diverges from effective capital, inspect effective capital in task details.

Single-Coin Position Cap & Total Notional Exposure

Concept	Constrains	Typical Misuse
Single-Coin Position Cap	Notional size of a single contract	Setting it higher than total capital, rendering it ineffective
Max Notional Exposure (Total Cap)	Sum of all notional positions	Confusing with capital, believing losses cannot exceed it

Notional Exposure = Mark Price × Quantity. It is distinct from margin. At 10x leverage, 100 USDT margin controls approximately 1,000 USDT in notional exposure.

Risk Multiplier

Intuitive formula: Whatever percentage of equity the lead trader uses for a trade, you use that same percentage of your capital, multiplied by the Risk Multiplier.

• Multiplier 1: Exact proportional replication.
• Multiplier 2: Your position is twice the trader's proportional size; volatility and loss risk roughly double.
• Range: 0.01 to 10; default is 1.

The Risk Multiplier is not a profit multiplier and does not boost win rates; it strictly amplifies the outcome of the strategy.

Leverage & Margin Mode

• Follow Trader: Uses the trader's current leverage; default setting.
• Fixed Leverage: Specify an integer between 1 and 125, only used when Fixed mode is selected.
• Margin Mode: Defaults to follow trader. If an existing position in that coin conflicts with this setting, opening orders are skipped with a clear reason in missed trade logs.

Actual effective leverage remains bound by exchange tier limits, especially for newly listed or highly volatile contracts.

Account Loss Budget

Shown under "Account Loss Budget · USDT", derived from account risk budget settings and cannot be edited inside an individual task (the UI explicitly indicates this). When triggered, only position reduction and closure are allowed; new positions are halted, and no automatic market dump occurs.

Budget-related locks ("Loss budget exhausted", "External deposit/withdrawal pending confirmation") halt new risk. Routine resumption cannot override them; administrator review is required.

Entry Rules & Risk Controls

Field	Meaning & Checkpoints
When Trader Has Existing Positions	"Better price only" requires lower market price for longs, higher for shorts; "Follow new orders only" waits for new signals.
Slippage Ceiling (bps)	Caps acceptable price divergence; 1 bp = 0.01%, 20 bps = 0.20%.
Chase Window (minutes)	Valid window for following a signal; expired signals are abandoned.
Max Drawdown Stop (%)	When reached, task transitions to reduce-only. Does not guarantee total liquidation or max loss cap; see termination actions to close out.
Symbol Whitelist / Direction Filter	Restricts eligible coins; confirm format and note that leaving blank means no restriction.

Handling Existing Trader Positions

When creating a task, the trader may already hold open positions. You must choose how to treat these historical holdings:

Option	Behavior	Best For
Better Price Only	Longs require current mark price < trader entry; Shorts require current mark price > trader entry	Default; avoids chasing tops or selling bottoms
Follow New Orders Only	Ignores existing positions completely; waits for new signals	Following future logic without inheriting past positions
Follow All (if available)	Copies all existing positions proportionally regardless of price	When you trust the trader's thesis and accept chasing

Available options may differ across releases. Pre-flight output details whether each existing position will be copied and projected quantities.

Slippage Ceiling (bps)

• Unit is basis points: 1 bp = 0.01%, 20 bp = 0.20%, 100 bp = 1%.
• Range: 1–1000 bps, default 20.
• If execution price deviates past this cap, the order is protectively skipped, logged in missed trades, and not chased repeatedly.
• Setting too tight (e.g. 1–3 bps) causes high missed trade rates; setting too loose allows significant price drift. Both erode returns in choppy markets.

Chase Window (minutes)

• Time window within which a signal can be chased; once expired, the signal is dropped.
• Range: 1–1440 minutes, default 5 minutes.
• Longer windows improve fill probability, but increase risk of entering far from the trader's entry price.
• Expired skips are logged as "Chase timeout (exceeded chase window)".

Task Drawdown Stop (%)

• Task-level drawdown threshold. When reached, the task switches to reduce-only and triggers a notification.
• Range: 0.1–100%, default 15%.
• Reaching the threshold does not mean positions are fully liquidated, nor is it a guaranteed loss cap; use "Stop Copy → Market Close & Stop" if complete closure is desired.
• Drawdowns evaluate against effective capital.

Symbol Whitelist & Direction Filter

• Separate symbols with commas, spaces, or slashes (e.g. BTC, ETH, SOL); auto-converted to uppercase.
• Leaving blank means no restriction, copying all coins traded by the lead trader.
• Use base asset symbols (1–32 alphanumeric chars); do not append quotes (use BTC, not BTCUSDT).
• Direction filters can restrict to Long Only, Short Only, or Both. Filtered signals log as "Triggered direction filter".
• Whitelist and blacklist cannot share common symbols.

Tip: Coin filtering is one of the most effective risk management tools. Restricting your whitelist to major coins like BTC, ETH, SOL eliminates low-liquidity surprises more reliably than lowering leverage.

Pre-flight & Launch Confirmation

Read all warnings, projected margin, and existing position outcomes returned by pre-flight before submitting. Never treat estimates as execution guarantees; modify parameters and re-verify if needed.

Confirm execution mode and risk notices before launch. After creation, inspect task details for live status and feedback. See FAQ for zero fill questions.

What Pre-flight Returns

Return Item	Meaning	How to Use
Copy Ratio	Proportional sizing derived from your capital vs trader equity	Verify if scale meets expectations
Existing Position Disposition	"Will follow / Will not follow" and projected quantity per coin	Decide whether to switch to "Follow new orders only"
Warnings List	Risk factors identified by server (e.g. high capital, account warnings)	Read every item before deciding to proceed
Blocking Errors	Illegal parameters, ineligible account, failed admission	Must be corrected; cannot be bypassed

Passing pre-flight does not guarantee fills or lock prices. Pre-flight is strictly tied to submitted values: any field edit invalidates pre-flight, requiring a new check.

Pre-Launch Confirmation Steps

1. Verify trader, API key, allocated capital, notional cap, and slippage in the summary card.
2. Read warnings. Prompts marked ⚠ will not block creation, but often indicate where real risk lies.
3. Check "I have reviewed account, parameters, and risks".
4. Click "Confirm & Launch Copy". Upon success, you are redirected to Task Details.

Common Blocking Issues

Prompt	Cause	Resolution
Enter a valid trader profile link or ID	Format mismatch	Paste full profile URL or raw ID
Select a verified API and read available capital	Unchecked key or balance read failure	Recheck key or click Re-read
Max allocatable is N USDT	Exceeds available balance or plan quota	Lower capital or stop idle tasks
Trader identity or position visibility unconfirmed	Secondary verification failed	Re-verify source and check trader
Live risk addition currently unavailable	Admission, auth, budget, or host policy	Review reason text; await clearance
Please check: Symbol whitelist...	Invalid format	Correct according to field instructions

After Creation

• The task appears in your "Copy Tasks" list; execution engine receipts are authoritative.
• Task details provide open positions, order fills, and execution receipts (latency, slippage, follow rate, missed trades).
• Use "Pause New Risk" to temporarily stop opening positions; use "Stop Copy" to terminate, choosing whether to market close positions.
• When facing "Running but no trades", check missed trade logs first; see Running but No Trades.
