Re-entry buy with LWMA 5 and 10 Low

Description of the ScriptThis script is designed for MetaTrader 4 (MT4) to execute a Buy order based on a re-entry strategy using the BBMA (Bollinger Bands Moving Average) approach. The main timeframe used is H1 (1-hour), and the script employs the Classic Bullish Engulfing pattern as a validation criterion before placing a Buy order.Key Components of the Script:Input Parameters:Lots: Defines the lot size for the trade (default is 0.1).LWMA5_Period: The period for the 5-period Linear Weighted Moving Average (LWMA) applied to the Low price on the H1 timeframe.LWMA10_Period: The period for the 10-period Linear Weighted Moving Average (LWMA) applied to the Low price on the H1 timeframe.EMA_Period: The period for the 50-period Exponential Moving Average (EMA) applied to the Close price on the H1 timeframe.Global Variables:lwma5Value: Stores the calculated value of the 5-period LWMA on the H1 timeframe.lwma10Value: Stores the calculated value of the 10-period LWMA on the H1 timeframe.emaValue: Stores the calculated value of the 50-period EMA on the H1 timeframe.Initialization and Deinitialization:The OnInit() and OnDeinit() functions are placeholders for initialization and cleanup code when the script is loaded or unloaded.OnTick Function:This is the main function that is executed every time a new tick (price change) is received.Inside OnTick():LWMA and EMA Calculation:The script calculates the 5-period LWMA (lwma5Value) and 10-period LWMA (lwma10Value) on the Low price of the H1 timeframe.It also calculates the 50-period EMA (emaValue) on the Close price of the H1 timeframe.Re-entry Signal Validation on H1:The script checks if the previous candle's Close price was below the 5-period LWMA and the current candle's Close price is above both the 5-period and 10-period LWMAs, as well as above the 50-period EMA.Check for Existing Orders:Before placing a new Buy order, the script checks if there is already an open Buy order to avoid multiple entries.Validation on M15 Timeframe:The script validates the conditions on the M15 (15-minute) timeframe:Classic Bullish Engulfing Pattern:The previous candle must be bearish (Close < Open).The current candle must be bullish (Close > Open), with its body "engulfing" the previous bearish candle's body (current Open < previous Close and current Close > previous Open).High Breakout Confirmation:Additionally, the current candle's Close price must break above the High of the previous candle.Stop Loss and Take Profit Calculation:Stop Loss: Calculated as the lowest Low between the current and previous candles on the M15 timeframe, with a small buffer of 5 points.Take Profit: Set at a 1:1 ratio with the Stop Loss distance.Order Execution:If all conditions are met, a Buy order is placed with the calculated Stop Loss and Take Profit.IsOrderOpen Function:This helper function checks if there is already an open Buy order for the current symbol to prevent multiple entries.Error Description Function:Provides descriptions for potential errors that may occur during order placement, improving debugging and error handling.Summary:The script executes a Buy order based on a re-entry strategy, validated by the Classic Bullish Engulfing pattern on the M15 timeframe and confirmed by the LWMA and EMA indicators on the H1 timeframe. The script includes safety checks to prevent multiple entries, and it calculates appropriate Stop Loss and Take Profit levels based on recent price action.
