Copy Trading Parameters

A full reference for every configuration option available in the copy trading setup. Fine-tune risk, sizing, and filtering to match your strategy.

Allocation

Controls how much USDC is placed on each copied trade.

Mode	Description	Example
`Fixed`	Place exactly N USDC on every copied trade, regardless of whale's position size.	$20 per trade
`Percentage`	Use a fixed % of your total wallet balance per trade. Adapts as your balance changes.	5% of balance
`Mirror`	Copy the whale's exact position size proportionally to your wallet vs. their balance.	Proportional to whale

ℹ️

Recommended for beginners: Start with Fixed mode at a small amount (e.g., $10–$25) while you observe which whales perform well before increasing allocation.

Max Bet

Sets the maximum amount PredyX will place on any single copied trade, regardless of your allocation setting. This is a hard cap — if the allocation formula would exceed it, the trade is capped at Max Bet.

Setting	Behavior
`Max Bet: $100`	No single trade will exceed $100, even if 5% of your $3,000 balance would be $150.
`Max Bet: Unlimited`	No cap. Allocation formula determines exact size.

Market Filter

Restricts copy trading to specific market categories. If the whale trades in a category not on your allow-list, that trade is skipped.

Available categories:

Politics Sports Crypto Finance Health Climate Entertainment Science All Markets

ℹ️

Selecting All Markets (default) copies trades across every category the tracked whale enters.

Only copy trades where the market price is within a specified range. Useful for avoiding trades at extreme probabilities (e.g., a market already at 98¢ YES has very little upside).

Parameter	Description	Default
Min Price	Skip trades below this probability (e.g., 0.05 = 5¢)	0.02
Max Price	Skip trades above this probability (e.g., 0.95 = 95¢)	0.98

Auto Stop-Loss

Automatically closes a copied position if it reaches a specified loss threshold, protecting your capital.

Parameter	Description
Stop-Loss %	Close position if current value drops by X% from entry. E.g., 50% stop-loss on a $50 trade exits when value reaches $25.
Enabled	Toggle auto stop-loss on/off. Off by default.

⚠️

Polymarket liquidity warning: During low-liquidity periods, the actual exit price may differ from the stop-loss target. PredyX uses market orders to exit, so slippage may apply.

Auto Take-Profit

Automatically closes a position when it reaches a specified profit level.

Parameter	Description
Take-Profit %	Exit when profit reaches X% of entry cost. E.g., 100% = double your money, then exit.
Enabled	Toggle auto take-profit on/off. Off by default.

Slippage Tolerance

Maximum acceptable price deviation when placing a trade. If the market moves beyond this before the order fills, the trade is cancelled.

Value	Behavior
`1%` (default)	Cancel trade if entry price moves more than 1% from the trigger price
`3%`	More tolerant — fills in more scenarios but may execute at a worse price
`0%`	Strict — only fills at exact trigger price. High cancellation rate in volatile markets

Copy Exits

When enabled, PredyX also copies the whale's exit trades — not just entries. If the whale closes a position you've copied, your position is closed at the same time.

ℹ️

Copy Exits is enabled by default. Disable it if you prefer to manage your exit timing independently.
