2. Risk Management Scenarios
Scenario 2.1: Daily Loss Limit Enforcement
Feature: Daily Loss Limit Enforcement
As a risk manager
I want to enforce daily loss limits
So that traders cannot exceed acceptable loss thresholds
Scenario: Trader exceeds daily loss limit
Given a trader has incurred $900 in losses today
And the daily loss limit is $1000
When the trader submits an order that would incur an additional $200 loss
Then the order should be rejected
And the trader should receive a "daily loss limit exceeded" error
Scenario: Trader approaches daily loss limit
Given a trader has incurred $950 in losses today
And the daily loss limit is $1000
When the trader submits an order that would incur an additional $75 loss
Then the order should be rejected
And the trader should receive a "approaching daily loss limit" warning
Scenario 2.2: Position Limit Enforcement
Feature: Position Limit Enforcement
As a risk manager
I want to enforce position limits
So that traders cannot accumulate excessive positions
Scenario: Trader exceeds position limit
Given a trader has 4 open positions
And the maximum open positions limit is 5
When the trader submits an order that would create a 6th position
Then the order should be rejected
And the trader should receive a "position limit exceeded" error
Scenario: Trader closes position to stay within limit
Given a trader has 5 open positions
And the maximum open positions limit is 5
When the trader submits an order to close one position
Then the order should be accepted
And the trader should be able to submit new positions afterward
3. Position Sizing Scenarios
Scenario 3.1: Fixed Contracts Sizing
Feature: Fixed Contracts Position Sizing
As a trader
I want to use fixed contracts sizing
So that I can control my position size precisely
Scenario: Calculate fixed contracts position
Given a trader uses fixed contracts sizing with 3 contracts
When the trader submits a buy order for ES
Then the position size should be exactly 3 contracts
Regardless of account size or market conditions
Scenario 3.2: Fixed Dollar Risk Sizing
Feature: Fixed Dollar Risk Position Sizing
As a trader
I want to use fixed dollar risk sizing
So that I can maintain consistent risk per trade
Scenario: Calculate fixed dollar risk position
Given a trader uses fixed dollar risk sizing with $200 risk per trade
And ES has a tick value of $12.50
And the trader's stop is 10 ticks away
When the trader submits a buy order for ES
Then the position size should be 2 contracts
Because $200 / (10 ticks * $12.50) = 2 contracts
4. Algorithmic Execution Scenarios
Scenario 4.1: TWAP Algorithm Execution
Feature: TWAP Algorithm Execution
As a trader
I want to execute orders using TWAP algorithm

When I submit a TWAP order with 1-minute intervals
Then the system should place 30 orders of approximately 3-4 contracts each
And each order should be spaced 1 minute apart
And the total execution should complete within 30 minutes
Scenario: TWAP order cancellation
Given I have submitted a TWAP order for 100 ES contracts
And 50 contracts have been executed
When I cancel the TWAP order
Then the remaining 50 contracts should not be executed
And any active orders should be cancelled
Scenario 4.2: VWAP Algorithm Execution
Feature: VWAP Algorithm Execution
As a trader
I want to execute orders using VWAP algorithm

When I submit a VWAP order with 10% participation rate
Then the system should place orders proportional to market volume
And the average execution price should be close to VWAP
And the total execution should complete within 30 minutes
Scenario: VWAP order with volume prediction
Given I have submitted a VWAP order with volume prediction enabled
When market volume is higher than average
Then the system should increase order size proportionally
And when market volume is lower than average
Then the system should decrease order size proportionally

So that I can hide large order sizes
Scenario: Execute Iceberg order successfully
Given I have a valid trading account with $100,000
And I want to buy 100 ES contracts with visible quantity of 10
When I submit an Iceberg order
Then the system should display only 10 contracts at a time
And as each displayed portion is filled, a new portion should be displayed
Until all 100 contracts are executed
Scenario: Iceberg order cancellation
Given I have submitted an Iceberg order for 100 ES contracts
And 50 contracts have been executed
When I cancel the Iceberg order
Then the remaining visible quantity should be cancelled
And no new portions should be displayed

As a trader
I want my orders routed intelligently
So that I get the best execution
Scenario: Route order to best venue
Given multiple execution venues are available
And venue A has lower costs but slower execution
And venue B has higher costs but faster execution
When I submit an order with cost priority
Then the order should be routed to venue A
And when I submit an order with speed priority
Then the order should be routed to venue B
Scenario: Route order based on venue performance
Given venue A has 99% fill rate
And venue B has 95% fill rate
When I submit an order without specific priority
Then the order should be routed to venue A

And the remaining 50 orders should be rejected
And the system should return a "rate limit exceeded" error
Scenario: Recover from rate limit
Given the global rate limit is 100 orders per second

As a system administrator
I want the circuit breaker to activate during failures
So that the system can recover gracefully
Scenario: Circuit breaker opens after failures
Given the failure threshold is 5 failures
When 5 consecutive order failures occur
Then the circuit breaker should open
And new orders should be rejected
And the system should return a "circuit breaker open" error
Scenario: Circuit breaker closes after timeout
