Tradingview - pine script for Take profit and Stop loss by percentage

I have a serious problem merging Take profit and Stop loss in one script.

I'm using this script for TP https://kodify.net/tradingview/orders/percentage-profit/

and this one for SL https://kodify.net/tradingview/orders/percentage-stop/

I came up with the below script which doesn't look to SL. Hence, the order will remain open until TP % is reached. I need your help to fix it and activate SL same as TP.

//@version=3
strategy(title="Take profit (% of instrument price)",
     overlay=true, pyramiding=1)

// STEP 1:
// Make inputs that set the take profit % (optional)
longProfitPerc = input(title="Long Take Profit (%)",
     type=float, minval=0.0, step=0.1, defval=3) * 0.01

longLossPerc = input(title="Long Stop Loss (%)",
     type=float, minval=0.0, step=0.1, defval=1) * 0.01

// Calculate moving averages
fastSMA = sma(close, 20)
slowSMA = sma(close, 60)

// Calculate trading conditions
enterLong  = crossover(fastSMA, slowSMA)


// Plot moving averages
plot(series=fastSMA, color=green)
plot(series=slowSMA, color=red)

// STEP 2:
// Figure out take profit price
longExitPrice  = strategy.position_avg_price * (1 + longProfitPerc)
longStopPrice  = strategy.position_avg_price * (1 - longLossPerc)




// Plot take profit values for confirmation
plot(series=(strategy.position_size > 0) ? longExitPrice : na,
     color=green, style=circles,
     linewidth=3, title="Long Take Profit")

plot(series=(strategy.position_size > 0) ? longStopPrice : na,
     color=red, style=cross,
     linewidth=2, title="Long Stop Loss")
// Submit entry orders
if (enterLong)
    strategy.entry(id="EL", long=true)



// STEP 3:
// Submit exit orders based on take profit price
if (strategy.position_size > 0)
    strategy.exit(id="TP", limit=longExitPrice)


if (strategy.position_size > 0)
    strategy.exit(id="SL", stop=longStopPrice)
