Need to create a simple box breakout strategy with limit order

Strategy Specification: Time-Based Breakout with Retracement Entry (Fully Mechanical)

Session Box Definition

• Time Window: Draw a box from 17:00 to 19:59 (UTC-4). from 17:00 new trading day begins and previous days unopened positions should be canceled but the open positions should be kept open until it hits tp or sl.
• Box Parameters:
  
• High of the box = highest price within the time window
• Low of the box = lowest price within the time window
• The box remains fixed for the rest of the trading day.  

Breakout Condition

• A breakout is confirmed only when a 15-minute candle closes with its body fully outside the box: (the only criteria is the body should be closed outside the box, it doesn’t matter how far the body closed or how big the wick is, which means even a minor body close is valid)
  
• Bullish breakout: candle body closes entirely above the box
• Bearish breakout: candle body closes entirely below the box
• 
  
• Wicks do not count as breakouts — only full body closures.

Entry Conditions

• Upon detecting a breakout:
  
• If bullish breakout, place a buy limit order at the top (high) of the box. 
• If bearish breakout, place a sell limit order at the bottom (low) of the box.
• 
  
• Retracement into the box is required to trigger the entry. so a limit order is needed for this strategy 

Stop Loss (SL) and Take Profit (TP)

• SL is always placed at the opposite edge of the box:
  
• Buy trade SL = bottom of the box
• Sell trade SL = top of the box
• 
  
• TP is always set to 1:3 Risk-to-Reward (fixed ratio), calculated based on the distance between entry and SL.

Risk Management

• The lot size must be calculated dynamically to risk exactly 1% of the account balance per trade, based on SL distance in pips. (this should be easily editable and should need instructions to do so)
• Trade is either a full win (TP hit) or full loss (SL hit). No partial exits.

Trade Rules

• Only one trade per day is allowed.
• If the limit order is not triggered by end of day, cancel it.
• After a TP or SL hit, no further trades are taken for the day. 

Parameters to Keep Editable

(These should be made user-configurable in input settings)all these parameters should be editable. I also need a source code of the strategy

1. Box start and end time (default: 17:00–19:59 UTC-4) - this part should be editable 
2. Risk percentage per trade (default: 1%) -this should be editable
3. Risk-to-reward ratio (default: 1:3)
4. Maximum trades per day (default: 1)
5. Time to cancel pending order (e.g., by midnight or user-defined).
