This code snippet demonstrates how to manage a trading strategy that involves multiple stages of position closing and setting a breakeven stop loss for the remaining position using ProBuilder language.

// Paramètres initiaux
NbContratsInitiaux = 3 // Nombre initial de contrats
NbContrats = NbContratsInitiaux // Variable pour suivre le nombre de contrats actuellement ouverts

// Conditions pour clôturer des contrats
IF longonmarket THEN
    IF NbContrats = NbContratsInitiaux AND positionperf > 0 THEN
        SELL 1 CONTRACT AT market // Clôturer 1 contrat à la première clôture gagnante
        NbContrats = NbContrats - 1
    ELSIF NbContrats = NbContratsInitiaux - 1 AND positionperf > 0 THEN
        SELL 1 CONTRACT AT market // Clôturer un second contrat à la bougie suivante gagnante
        NbContrats = NbContrats - 1
        SET STOP breakeven // Mettre le dernier contrat en breakeven
    ENDIF
ENDIF

// Même logique pour les positions courtes (si nécessaire)
IF shortonmarket THEN
    // Votre logique pour les positions courtes ici
ENDIF

This script is structured to handle a trading strategy where positions are closed in stages as profits are realized, and a breakeven stop loss is set for the final position. Here’s a breakdown of the code:

• Initial Setup: The script starts by defining the initial number of contracts and a variable to track the number of open contracts.
• First Closure: If the market is long and the position is profitable (positionperf > 0) with all initial contracts still open, it closes one contract. The number of open contracts is then decremented.
• Second Closure: If one contract has already been closed and the position remains profitable, it closes another contract. Following this, it sets a breakeven stop loss for the last remaining contract.
• Handling Short Positions: The script also includes a placeholder for similar logic to be applied to short positions, which needs to be defined according to specific trading strategies.

This example is useful for understanding how to programmatically manage trades in stages and adjust stop losses dynamically based on the trading conditions and performance.
