Let's break down what's causing this compilation error and how to fix it quickly.

The Root Cause #

Your error message points to a syntax issue in your plotshape calls: the compiler can't parse the parameters because you're mixing named arguments (like title="SuperTrend Long") with unlabeled positional arguments incorrectly.

In Pine Script, once you use a named argument for any parameter, all subsequent parameters must also use their explicit parameter names. Your code skips labels for critical parameters like shape, location, and color after using title=, which confuses the parser.

Fixed Code Snippets #

Here's the corrected version of your plotshape blocks, with all parameters properly labeled:

// Plot entries
plotshape(cross(close,Tsl) and close>Tsl ? True : na, title="SuperTrend Long", shape=shape.triangleup, text="Buy", location=location.belowbar, color=color.green, transp=0) // Super Trend Long
plotshape(cross(Tsl,close) and close<Tsl ? True : na, title="SuperTrend Short", shape=shape.triangledown, text="Sell", location=location.abovebar, color=color.red, transp=0) // Super Trend Short
plotshape(longToggle ? (k <= kMin and Trend == 1 ? Trend : na) : na, title="Long Entry", shape=shape.labelup, location=location.belowbar, color=color.navy, transp=0, textcolor=color.black) // Stochastic Long Entry
plotshape(longAltToggle ? (rising(k,1) and cross(k, 50) and Trend == 1 ? Trend : na) : na, title="Long Alt Entry", shape=shape.cross, location=location.belowbar, color=color.olive, transp=0, textcolor=color.black) // Stochastic Long Entry
plotshape(longExitToggle ? (k >= kMax and Trend == 1 ? Trend : na) : na, title="Long Exit", shape=shape.xcross, location=location.abovebar, color=color.red, transp=0, textcolor=color.black) // Stochastic Long Exit
plotshape(shortToggle ? (k >= kMax and Trend == -1 ? Trend : na) : na, title="Short Entry", shape=shape.labeldown, location=location.abovebar, color=color.navy, transp=0, textcolor=color.black) // Stochastic Short Entry
plotshape(shortAltToggle ? (falling(k,1) and cross(k, 50) and Trend == -1 ? Trend : na) : na, title="Short Alt Entry", shape=shape.cross, location=location.abovebar, color=color.olive, transp=0, textcolor=color.black) // Stochastic Short Entry
plotshape(shortExitToggle ? (k <= kMin and Trend == -1 ? Trend : na) : na, title="Short Exit", shape=shape.xcross, location=location.belowbar, color=color.red, transp=0, textcolor=color.black) // Stochastic Short Exit

Key Changes Made #

1. Added explicit parameter labels (shape=, location=, color=) for all arguments after title= to resolve parsing confusion
2. Replaced the unlabeled black parameter with textcolor=color.black (this was the missing label for text color)
3. Removed the empty string "" parameter which was unnecessary and causing additional parsing issues

Why This Works #

Pine Script's parser relies on consistent argument labeling to map values to the correct function parameters. By explicitly naming each parameter, you eliminate ambiguity and ensure the compiler can translate your code correctly.

Just replace your original plotshape blocks with these corrected versions, and your script should compile without errors.
