Spot Grid

Why two assets are required

A spot grid requires both:

• Quote asset (e.g., USDC) → for buy orders

• Base asset (e.g., BTC) → for sell orders

Orders are pre-calculated based on:

• Price range

• Grid count

• Total investment

What is a Deficit?

A deficit is the missing base asset required to place all sell orders.

Example:

• Grid: BTC/USDC, range $90–$110

• Current price: $100

• Required BTC for sell orders: 0.5 BTC

• Available: 0.2 BTC

→ Deficit = 0.3 BTC

Deficit Status

• Deficit = 0 → No action needed

• Deficit > 0 → You must choose a funding method

Funding Options: Borrow Mode vs Buy Mode

	Borrow Mode	Buy Mode
How it works	Borrow base asset	Buy base asset using USDC
Upfront cost	None	Reduces USDC immediately
Ongoing cost	Interest accrues	None

Note: Buy Mode uses Max Entry Price to cap purchase price (default ≈ 1% above current price).

Auto Selection Logic

The system selects the funding mode automatically:

• Enough base asset → No funding

• Only one mode available → Uses that mode

• Both available → Defaults to Borrow Mode (can switch manually)
