Titik Impas Breakeven:

While manually adjusting the stop-loss of a single trade to match its open price is a relatively simple task, managing numerous positions individually can be cumbersome and time-intensive. The Titik Impas Breakeven script for MT4/MT5 streamlines this process, providing efficiency and convenience for traders dealing with multiple positions.

Dear Muhammad,

I stumbled upon your code, it is really nice. Thank you so much.

I have some corrections for the math calculations in your code:

1. avoid negative int inputs.

//input int MinimumProfit = 0;          // Minimum current profit in points to apply BE
//input int AdditionalProfit = 0;       // Additional profit in points to add to BE
input uint MinimumProfit = 0;          // Minimum current profit in points to apply BE
input uint AdditionalProfit = 0;       // Additional profit in points to add to BE

2. the right way to compare doubles.

        // Compare doubles by calculating difference. If this difference is greater than Point / 2, the position's profit is below the MinimumProfit parameter.
        //if ((MinimumProfit > 0) && ((double)MinimumProfit - MathAbs(PositionGetDouble(POSITION_PRICE_OPEN) - PositionGetDouble(POSITION_PRICE_CURRENT)) / point > point / 2)) continue;
        if ((MinimumProfit > 0) && ((double)MinimumProfit * point >= MathAbs(PositionGetDouble(POSITION_PRICE_OPEN) - PositionGetDouble(POSITION_PRICE_CURRENT)) + point / 2) continue;

3. rounding should not be done at the intermediate calculations not to lose precision.

        //if (tick_size > 0)
        //{
        //    // Adjust for tick size granularity.
        //    extra_be_distance = NormalizeDouble(MathRound(extra_be_distance / tick_size) * tick_size, digits);
        //}

4. rounding should only be done in the final step of calculations to chop fp roundoff errors.

        if (PositionGetInteger(POSITION_TYPE) == POSITION_TYPE_BUY)
        {
            double BE_price = NormalizeDouble(PositionGetDouble(POSITION_PRICE_OPEN) + extra_be_distance, digits);
            if (tick_size > 0)
            {
                // Adjust for tick size granularity.
                BE_price = MathRound(BE_price / tick_size) * tick_size;
            }
            ...
            ...
            
        else if (PositionGetInteger(POSITION_TYPE) == POSITION_TYPE_SELL)
        {
            double BE_price = NormalizeDouble(PositionGetDouble(POSITION_PRICE_OPEN) - extra_be_distance, digits);
            if (tick_size > 0)
            {
                // Adjust for tick size granularity.
                BE_price = MathRound(BE_price / tick_size) * tick_size;
            }            
            ...
            ...
