This ProBuilder code snippet demonstrates how to implement a trading pause for a specified number of bars after incurring a loss in a trading strategy. The purpose is to avoid entering new trades immediately after a losing trade, which can be part of a risk management strategy.

if not onmarket and onmarket[1] and positionperf(1)<0 then
    mybar = barindex[1]
endif

if barindex-mybar>X then
    autorisetrading = 1
else
    autorisetrading = 0
endif

if autorisetrading then
    //ACHAT
    if conditionachat then
        buy 1 contract at market
    endif
    //VENTE
    if conditionvente then
        sellshort 1 contract at market
    endif
endif

Explanation of the code:

• Checking the last trade result: The first if statement checks if the market is not currently in a trade, but was in the previous bar (onmarket[1]), and the last position resulted in a loss (positionperf(1)<0). If these conditions are met, it records the bar index of the last trade's closure in mybar.
• Implementing the trading pause: The second if statement checks if the current bar index minus mybar is greater than X (where X is the number of bars to pause trading after a loss). If true, trading is authorized (autorisetrading = 1); otherwise, it is not authorized (autorisetrading = 0).
• Executing trades: The final if statement allows new trading actions if trading is authorized. Inside this block, there are two conditions: one for buying (conditionachat) and one for selling (conditionvente). If the respective condition is true, a trade is executed either by buying or selling short one contract at the market price.

This snippet is useful for traders who want to incorporate a cooling-off period into their automated strategies to potentially reduce risk after a losing trade.
