ORB Strategy Combined is a sophisticated algorithmic trading robot based on the Opening Range Breakout (ORB) concept. It is designed to capture volatility immediately following the market open by defining a high/low range over a specific period (e.g., 15 minutes).

Key Features:

• Dual Entry Modes:
• • Stop Mode (Breakout): Places a bracket of Buy Stop and Sell Stop orders at the ORB High/Low. Logic includes a unique re-entry mechanism: if a trade closes (TP or SL), the bot waits for price to retrace to the ORB Mid-point before placing a new breakout order.
  • Limit Mode (Fade/Retest): Waits for price to break out and places Limit orders at the ORB edge to catch a retest. Includes a "Run-away Cancel" feature if price moves too far without filling the order.
• Flexible Targets: Choose between Dynamic Ratios (based on the size of the ORB candle) or Fixed Pips for Stop Loss and Take Profit.
• Smart Filters:
• • EMA Filter: Ensures trades align with the broader trend.
  • PDH/PDL Filter: Prevents buying into a Previous Day High or selling into a Previous Day Low if the Take Profit is obstructed.
• Risk Management: Includes % Equity risk sizing, Auto-Break-Even, Session End closure, and a hard cap on Max Trades per session.

Parameters in Detail

1. Strategy Setup

• Entry Order Type:
• • Limit: Places Limit orders at the ORB lines. Best for "Break and Retest" strategies.
  • Stop: Places Stop orders at the ORB lines immediately when the range closes. Best for "Momentum Breakout" strategies.
• ORB Period (Minutes): The duration of the opening range (e.g., 15 means the bot calculates the High/Low of the first 15 minutes of the session).

2. Risk & Targets

• Target Mode:
• • Ratio: Calculates SL/TP based on the height of the ORB range (Volatility adjusted).
  • FixedPips: Uses a static number of pips for SL/TP regardless of range size.
• Risk Percent: The percentage of your account balance to risk per trade (Lot size is calculated automatically).

Ratio Settings (Active if Target Mode = Ratio):

• TP Ratio: Multiplier for Take Profit. (e.g., 1.0 = 1x the ORB size).
• SL Ratio: Multiplier for Stop Loss. (e.g., 1.0 = 1x the ORB size).

Pips Settings (Active if Target Mode = FixedPips):

• Fixed TP (Pips): The Take Profit distance in pips.
• Fixed SL (Pips): The Stop Loss distance in pips.

3. Trade Management

• Cancel RR Ratio (Limits only): Applies only to Limit Mode. If the price moves away from the entry by this ratio (relative to risk) before filling the order, the pending order is cancelled. (e.g., Price runs 10.5 R towards TP without triggering entry).
• Move to BE RR Ratio: When the trade is in profit by this Risk Ratio (e.g., 1.0 = 1x Risk), the Stop Loss is moved to Break Even.
• BreakEven Offset (pips): How many pips past the entry price to place the Break Even SL (to cover commissions).
• Re-Enter at ORB Break after TP?:
• • True: If a trade hits TP, the bot waits for price to touch the ORB Mid line. Once touched, it places a new pending order for the same direction.
  • False: One trade per direction per session (unless stopped out, where re-entry logic always applies).
• Close Trades on Session End?: If True, all open positions and pending orders are closed at the Session End time.
• Max Trades Per Session: A hard limit on the number of trades allowed per day. If reached, all pending orders are cancelled immediately.

4. Time Settings

• Session Start (HH:mm UTC): The specific time the bot starts measuring the ORB range.
• Session End (HH:mm UTC): The time the bot stops trading and (optionally) closes positions.

5. EMA Filter

• Enable EMA Filter: If True, the bot checks the Exponential Moving Average.
• • Buy Rule: Price must be > EMA.
  • Sell Rule: Price must be < EMA.
• EMA Period: The length of the EMA (e.g., 200).
• EMA TimeFrame: The timeframe used for the EMA calculation (e.g., Hour1, even if trading on Minute5).

6. PDH/PDL Filter

• Enable PDH/PDL Filter: If True, the bot checks the Daily High/Low of the previous day.
• • Logic: It blocks a trade if the Previous Day High is between your Entry and TP (for Buys), or if the Previous Day Low is between Entry and TP (for Sells).

7. Trading Days

• Trade on Monday - Sunday: Toggles trading permission for specific days of the week.
