hello im trying change pinescript strategy to indicator with alert conditions

Question

Hello im trying to change this strategy to indicator with alert condition and still run strategy concept.the part im stuck on is strategy.opentrades, i use this to stop looking for trades if current trade not closed. also strategy.exit i use to close trade

//strategy("2Ma cross ATR Bands strategy", overlay = true) 

// Inputs
atrPeriod = input(3, "ATR Period") // Period for calculating Average True Range (ATR)
srcUpper = input(defval = close, title = "Source Upper") // Source for Upper ATR Band
srcLower = input(defval = close, title = "Source Lower") // Source for Lower ATR Band
atrMultiplierUpper = input(title = "ATR Multiplier Upper", defval = 4.0, tooltip ="3.8" ) // Multiplier for Upper ATR Band
atrMultiplierLower = input(title = "ATR Multiplier Lower", defval = 3.0, tooltip = "2.5") // Multiplier for Lower ATR Band

// Calculate ATR
atr = ta.atr(atrPeriod)

// Plotting
plot(srcUpper + atr * atrMultiplierUpper, color = color.green) // Plot the Upper ATR Band
plot(srcLower - atr * atrMultiplierLower, color = color.red) // Plot the Lower ATR Band
plot(ta.sma(close, 10)) // Plot a simple moving average for reference


// Entry condition
buysign = ta.crossover(close, ta.sma(close, 10)) // Buy signal when close crosses above the 10-period SMA
//buysign2 = ta.crossover(close, xATRTrailingStop)


tp2 =srcUpper + atr * atrMultiplierUpper // Calculate Take Profit
sl2 = srcLower - atr * atrMultiplierLower // Calculate Stop Loss

//================================

plotshape(buysign,"buy", shape.triangledown, color = color.green)


// Plot TP and SL lines as dashed lines
if buysign and strategy.opentrades == false //alertcomdition
    strategy.entry("long", strategy.long)
    line.new(bar_index, low, bar_index, tp2, width=2, color=color.rgb(154, 103, 20), style=line.style_dashed)
    tpLine = line.new(bar_index, tp2, bar_index + 3, tp2, width=2, style=line.style_dashed, color=color.rgb(154, 103, 20))
    label.new(bar_index + 1, tp2, "TP", color=color.rgb(17, 255, 0, 83), style=label.style_label_left, size=size.tiny, textcolor=color.white)
   

// Plot SL as dashed line
    line.new(bar_index, high, bar_index, sl2, width=2, color=color.rgb(154, 103, 20), style=line.style_dashed)
    slLine = line.new(bar_index, sl2, bar_index + 3, sl2, width=2, style=line.style_dashed, color=color.rgb(154, 103, 20))
    label.new(bar_index + 1, sl2, "SL", color=color.rgb(255, 0, 0, 90), style=label.style_label_left, size=size.tiny, textcolor=color.white)
    strategy.exit("long", stop = sl2, limit = tp2) //alertcomdition

Answer 1

Just use a var flag to see if you are in a long position. Set it to true whenever your entry condition is true and set it to false whenever your exit condition is true.

var is_long = false

buysign = not is_long and ta.crossover(close, ta.sma(close, 10)) // Buy signal when close crosses above the 10-period SMA

if (buysign)
    is_long := true

if (your_exit_signal)
    is_long := false
