Converting TradingView Indicator to Pine Script Strategy

Answered using GPT-4o Mini by GPT4oMini.app

Question:

You are a professional PineScript version=5 developer. You know how to code indicators and strategies and you also know their diffrences in code. I need your help to turn a tredingview indicator into a strategy please.

Respect these instructions:

  • Convert all indicator specfic code to strategy specfic code. Don't use any code that a TradingView Strategy won't support. Especially timeframes and gaps. Define those in code so they are semnatically the same as before.

  • Preserve the timefrane logic is there is one. Fill gaps.

  • If the indicator is plotting something, the strategy code shall plot the same thing as well so the visuals are preserved.

  • Don't trigger a short. Simply go Long and Flat.

  • always use 100% of capital.

  • Set commission to 0.1%

  • Set slippage to 3.

  • strategy.commission.percent and strategy.slippage don't exist in PineScript. Please avoid this mistake. Set those variables in the strategy() function when initating the strategy.

  • When initiating the strategy

Answer:

Sure! To convert a TradingView indicator into a strategy in Pine Script version 5, we need to follow your instructions closely. Below is a template that demonstrates how to convert an indicator into a strategy while adhering to your requirements.

Example Indicator Code

Let's assume we have a simple moving average crossover indicator as our starting point. The indicator plots two moving averages and generates buy signals when the short moving average crosses above the long moving average.

//@version=5
indicator("Simple MA Crossover", overlay=true)
shortMA = ta.sma(close, 9)
longMA = ta.sma(close, 21)

plot(shortMA, color=color.blue, title="Short MA")
plot(longMA, color=color.red, title="Long MA")

buySignal = ta.crossover(shortMA, longMA)
plotshape(buySignal, style=shape.labelup, location=location.belowbar, color=color.green, size=size.small, title="Buy Signal")

Converted Strategy Code

Now, let's convert this indicator into a strategy while following your instructions:

//@version=5
strategy("Simple MA Crossover Strategy", overlay=true, default_qty_type=strategy.percent_of_equity, default_qty_value=100, commission_type=strategy.commission.percent, commission_value=0.1, slippage=3)

// Define the moving averages
shortMA = ta.sma(close, 9)
longMA = ta.sma(close, 21)

// Plot the moving averages
plot(shortMA, color=color.blue, title="Short MA")
plot(longMA, color=color.red, title="Long MA")

// Define the buy signal
buySignal = ta.crossover(shortMA, longMA)

// Execute the buy order
if (buySignal)
    strategy.entry("Long", strategy.long)

// Optional: Close the position when a certain condition is met (e.g., when the short MA crosses below the long MA)
// This is just an example; you can modify the exit condition as needed.
if (ta.crossunder(shortMA, longMA))
    strategy.close("Long")

Key Changes Made:

  1. Strategy Initialization: The strategy() function is used instead of indicator(), with parameters for commission and slippage.
  2. Entry Logic: The strategy only goes long when the buy signal is triggered.
  3. Exit Logic: An exit condition is added to close the long position when the short MA crosses below the long MA. This is optional and can be modified based on your requirements.
  4. Plotting: The moving averages are still plotted for visual reference.

Notes:

  • Ensure that the logic for entering and exiting trades aligns with your trading strategy.
  • You can customize the moving average lengths or any other parameters as needed.
  • If you have a specific indicator in mind, please provide the code, and I can help you convert that specific indicator into a strategy.
