The script is defined as a strategy to enable backtesting. - It overlays on the main chart and sets an initial capital of $10,000. 2. **User Inputs:** - **Account Balance:** Allows the trader to input their account balance (default is $10,000). - **Risk Percentage:** The percentage of the account balance the trader is willing to risk per trade (default is 2%). - **Stop-Loss Distance:** The distance for the stop-loss in pips (default is 50 pips). - **Risk-Reward Ratio:** Set to 2 for a 2:1 risk-reward ratio. 3. **Position Size Calculation:** - **Risk Amount:** Calculates the dollar amount to risk per trade based on the account balance and risk percentage. - **Pip Size:** Defines the pip size based on the symbol. For most Forex pairs, 1 pip = 0.0001. Adjusts to 0.01 for JPY pairs. - **Stop-Loss Price:** Calculates the stop-loss price based on the current close minus the stop-loss distance in pips. - **Take-Profit Price:** Calculates the take-profit price based on the risk-reward ratio. - **Pip Value:** Assumes a pip value of $10 per standard lot. - **Position Size (Lots):** Determines the number of lots to trade based on the risk amount, stop-loss pips, and pip value. 4. **Plotting:** - **Position Size Label:** Displays the calculated position size on the chart. - **Stop-Loss and Take-Profit Levels:** Plots horizontal lines on the chart to indicate stop-loss and take-profit levels. 5. **Trading Signals:** - **Moving Averages:** Uses simple moving averages (fast and slow) to generate buy and sell signals. - **Entry Conditions:** Enters a long position when the fast MA crosses above the slow MA and a short position when the fast MA crosses below the slow MA. - **Exits:** Sets stop-loss and take-profit levels for each trade based on the calculated prices. 6. **Alerts:** - **Stop-Loss Alert:** Sends an alert when a stop-loss is triggered. - **Take-Profit Alert:** Sends an alert when a take-profit is triggered. 7. **Backtesting:** - The strategy is set to backtest over the last 1 year based on the chart's timeframe and date range. 8. **Risk-Reward Visualization:** - Optionally, visual elements like dotted lines can be added to enhance the visualization of entry, stop-loss, and take-profit levels. ### **Usage Instructions:** 1. **Adding to TradingView:** - Open TradingView and navigate to the Pine Script editor. - Create a new script and paste the above code. - Save and add the strategy to your chart. 2. **Customization:** - Adjust the account balance, risk percentage, stop-loss pips, and moving average lengths through the input fields. 3. **Backtesting:** - The strategy will automatically backtest over the available historical data. To focus on the last 1 year, adjust the chart's timeframe and date range accordingly. 4. **Alerts:** - Set up alerts in TradingView based on the alert conditions defined in the script to receive real-time notifications when stop-loss or take-profit levels are hit. ### **Notes:** - **Position Sizing:** The script calculates position size in lots. For Forex trading, 1 standard lot is typically 100,000 units of the base currency. - **Symbol Compatibility:** Ensure the pip size is correctly defined for the symbols you are trading. The script adjusts for JPY pairs, but additional adjustments may be necessary for other instruments. - **Risk Management:** Always ensure that the risk management parameters align with your overall trading strategy and risk tolerance.
