This ProBuilder code snippet demonstrates how to implement a trading suspension mechanism that pauses trading activities after a specified number of consecutive losing trades. The system resumes trading after a certain time has elapsed.
Add TRADEOK to your entry conditions.
AllowedLosingTrades = 2
once tradeok = 1
if strategyprofit < strategyprofit[1] then
losercount = losercount + 1
endif
if losercount = AllowedLosingTrades then
tradeok = 0
restarttime = time + 010000
if restarttime >= 240000 then
restarttime = time - 230000
endif
endif
if not tradeok and time = restarttime then
tradeok = 1
losercount = 0
endif
The code snippet above is structured to control trading based on the recent performance of the strategy, specifically targeting losing trades. Here’s a step-by-step breakdown:
- Initialization: The variable TRADEOK is added to the entry conditions to control whether new trades can be initiated. AllowedLosingTrades is set to 2, representing the threshold of consecutive losing trades allowed before pausing trading.
- Tracking Losses: The system checks if the current strategy profit is less than the previous period’s profit. If true, it increments the losercount by 1.
- Suspending Trading: If losercount equals AllowedLosingTrades, trading is paused (tradeok is set to 0), and a restarttime is calculated by adding 010000 to the current time. This addition represents the time delay (in the format HHMMSS) after which trading can resume.
- Handling Overflow: There’s a check to ensure that restarttime does not exceed 240000 (the representation of time in HHMMSS format). If it does, it adjusts restarttime by subtracting 230000 from the current time to wrap around the clock correctly.
- Resuming Trading: The system checks if trading is paused and if the current time matches restarttime. If both conditions are true, trading is resumed (tradeok is set back to 1) and losercount is reset to 0.
This mechanism is useful for strategies that need to pause and reassess after a series of losses, potentially avoiding further drawdowns during unfavorable market conditions.
