The Trading Interface

When you arrive on the trading page, you see the full interface:

In this example:

BTC price = $67,035

Step 1 — Choose Call or Put

First, decide your market direction:

Call → you expect the price to go up
Put → you expect the price to go down

Step 2 — Select Asset and Strike Price

Next, choose:

The asset (e.g. BTC)
The strike price (from available liquidity)

👉 The strike price defines the price at which you can buy or sell the asset.

Step 3 — Choose Liquidity and Position Size

At each strike, liquidity providers offer:

Available liquidity
Associated APR (rental cost)

You can:

See how much liquidity is available
Select how much you want to use
Adjust your position size

👉 Your position size directly impacts your rent cost.

Step 4 — Understand the Cost

Before opening the trade, you can see:

Weekly rent cost
Effective APR

👉 This is the cost you pay to keep the position open.

Step 5 — Review Position Summary

Before confirming, review your contract:

Example:

Option Type: CALL
Asset: Bitcoin (BTC)
Strike Price: $70,000
APR: 70%
Amount: 0.012 BTC
Weekly Rent Cost: $11.31

Important: Collateral Requirement

Before opening a position:

👉 You must deposit collateral

This collateral must cover:

At least 2 weeks of rent

This ensures:

Your position can remain active
The protocol remains stable

After Opening Your Trade

Once your position is live:

👉 You can monitor it in your dashboard

You will see:

All open positions
Strike prices
Current PnL
Ongoing rent paid

Managing Your Position

At any time, you can:

Close your position
Keep it open and continue paying rent
Exercise your option

Exercising Your Option (Physical Settlement)

Scall.io uses physically settled options.

This means:

👉 When you exercise, the contract is fully executed.

Call Option

If you exercise a call:

You pay the strike price
You receive the asset

Example:

Strike = $70,000
Market price = $100,000

👉 You pay $70,000 and receive 1 BTC worth $100,000

Put Option

If you exercise a put:

You deliver the asset
You receive cash at strike price

Key Principle

👉 You must honor the full contract

There is no cash difference settlement.

This is real asset delivery.

Why This Matters

Physical settlement creates:

Real market interaction
No synthetic shortcuts
Stronger link between liquidity and execution
