This code snippet demonstrates how to implement different stop loss strategies in trading using the ProBuilder language. The strategies include a fixed stop loss, a fixed percentage below the Simple Moving Average (SMA), and a dynamic stop loss that updates based on the SMA.

// Fixed Stop Loss below SMA50
Sma50 = average[50,0](close)
MyLongConditions = close CROSSES OVER average[10,0](close)
IF MyLongConditions AND Not OnMarket THEN
    BUY 1 Contract at Market
    Sl = close - Sma50
    Tp = Sl * 2
    SET TARGET PROFIT Tp
    SET STOP LOSS Sl
ENDIF

// Fixed Stop Loss at 1% below SMA50
Sma50 = average[50,0](close)
MyLongConditions = close CROSSES OVER average[10,0](close)
IF MyLongConditions AND Not OnMarket THEN
    BUY 1 Contract at Market
    Sl = close - (Sma50 * 0.99)
    Tp = Sl * 2
    SET TARGET PROFIT Tp
    SET STOP LOSS Sl
ENDIF

// Dynamic Stop Loss at 1% below SMA50
Sma50 = average[50,0](close)
IF LongOnMarket THEN
    Sl = TradePrice - (Sma50 * 0.99)
    SET STOP LOSS Sl
ENDIF
MyLongConditions = close CROSSES OVER average[10,0](close)
IF MyLongConditions AND Not OnMarket THEN
    BUY 1 Contract at Market
    Sl = close - (Sma50 * 0.99)
    Tp = Sl * 2
    SET TARGET PROFIT Tp
    SET STOP LOSS Sl
ENDIF

The code is structured into three main parts, each implementing a different type of stop loss strategy:

• Fixed Stop Loss below SMA50: This section sets a stop loss exactly at the difference between the current close price and the SMA50. The target profit is set to twice the stop loss value.
• Fixed Stop Loss at 1% below SMA50: Similar to the first, but the stop loss is set 1% below the SMA50. This provides a cushion against market volatility.
• Dynamic Stop Loss at 1% below SMA50: This part updates the stop loss dynamically to always be 1% below the SMA50 for ongoing trades. It adjusts the stop loss as the SMA50 changes, which can be beneficial in trending markets.

Each section checks for a long entry condition based on the crossover of the close price over a shorter SMA (SMA10), and if the condition is met and there is no open position, it executes a buy order. The stop loss and target profit are then set according to the respective strategy.
