Pine Script. strategy.exit for Trailing Stop and Partial Take Profit

Question

I'm trying to have two exits on my strategy, one as a partial take profit and the other a trailing stop loss. I found some codes on the internet and I'm trying to put them together, but the trailing stop loss isn't working. It seams is something related to the order of the code. If I put the execution of the trailing stop before the partial take profit, the trailing stop works but the partial TP doesn't. I would appreciate some help. Thank you.

Your Trailing SL code looks correct

You wrote the same strategy.exit ID for

if strategy.position_size > 0
    strategy.exit(id='Trailing Long', stop=longStopPrice, alert_message="close BTCUSDT a=usdm")
    
if strategy.position_size < 0
    strategy.exit(id='Trailing Short', stop=shortStopPrice, alert_message="close BTCUSDT a=usdm")

2/ With the below, the x4 exit won't be executed because x1 is closing 50% of the initial position, x2 25% of the initial position and x3 25% of the initial position. So... there is nothing left for x4 to close

strategy.exit("x1", qty_percent = 50, profit = percentAsPoints(5), comment = "Loss")//, loss = lossPnt)
strategy.exit("x2", qty_percent = 25, profit = percentAsPoints(20), comment = "Loss")//, loss = lossPnt)
strategy.exit("x3", qty_percent = 25, profit = percentAsPoints(30), comment = "Loss")//, loss = lossPnt)
strategy.exit("x4", profit = percentAsPoints(4), comment = "Loss")//, loss = lossPnt)

Thanks for the answer Daveatt, I changed the exit ID, no success. Related to the x4, I know, I was just playing with the % to do some tests. — xBruV, Sep 23 '22 at 06:49
