This code snippet demonstrates how to implement dynamic exit strategies in trading algorithms using the ProBuilder language. It includes two distinct strategies for exiting trades based on market conditions and price movements.

// support & resistence once supportresistance = 0 // exit [0-1-2] // timeframe(30 seconds)
if supportresistance then
    pivotbar = 20
    lookback = 20
    barlookback = pivotbar + 1
    if low[pivotbar] < lowest[lookback](low)[barlookback] then
        if low[pivotbar] = lowest[barlookback](low) then
            supportprice = low[pivotbar]
        endif
    endif
    if high[pivotbar] > highest[lookback](high)[barlookback] then
        if high[pivotbar] = highest[barlookback](high) then
            resistanceprice = high[pivotbar]
        endif
    endif
endif
timeframe(default)
if supportresistance=1 then
    if ((longonmarket and shortonmarket[1]) or (longonmarket and not onmarket[1])) then
        sup=supportprice
    endif
    if ((shortonmarket and longonmarket[1]) or (shortonmarket and not onmarket[1])) then
        res=resistanceprice
    endif
elsif supportresistance=2 then
    sup=supportprice
    res=resistanceprice
endif
if supportresistance=1 or supportresistance=2 then
    if longonmarket then
        sell at sup stop
    endif
    if shortonmarket then
        exitshort at res stop
    endif
endif

    duration=360 // 720 = 1 hour lookback on 5s
    breakvalue=0
    if not onmarket then
        prell=0
        prehh=0
    endif
    if longonmarket then
        prehh=highest[max(1,(barindex-tradeindex))](high)
    endif
    if ((longonmarket and shortonmarket[1]) or (longonmarket and not onmarket[1])) then
        prell=lowest[duration](low)
    endif
    if shortonmarket then
        prell=lowest[max(1,(barindex-tradeindex))](low)
    endif
    if ((shortonmarket and longonmarket[1]) or (shortonmarket and not onmarket[1])) then
        prehh=highest[duration](high)
    endif
    if onmarket then
        fibpivot=(prehh-prell)*0.618
    else
        fibpivot=0
    endif
    if exitpivot=1 then
        if longonmarket then
            sell at (prehh-fibpivot)-breakvalue stop
        endif
        if shortonmarket then
            exitshort at (prell+fibpivot)+breakvalue stop
        endif
    endif
    if exitpivot=2 then
        if longonmarket then
            sell at prell-breakvalue stop
        endif
        if shortonmarket then
            exitshort at prehh+breakvalue stop

The code is structured into two main parts, each defining a different exit strategy:

• Support and Resistance Strategy: This part of the code calculates support and resistance levels based on historical price data. If the current price breaks these levels, the position is closed. This strategy is useful for markets that exhibit strong levels of support or resistance.
• Fibonacci Pivot Strategy: This strategy uses Fibonacci retracement levels to determine exit points. It calculates the highest and lowest prices since the trade was opened and applies the Fibonacci ratio to these values to find potential reversal points. This is particularly useful in trending markets where retracements can indicate potential reversals.

Both strategies are designed to help manage risk by specifying conditions under which a trade should be exited, potentially protecting gains or minimizing losses.
