Section 2: Basics

Basic, but important..

When you open your Pine Editor, you should see the Version number at the top few rows.
PineConnector

If your script is on Version 3,
you may convert it easily by clicking the ellipsis (⋯) followed by "convert to v4".

Comments
  • Any text that starts with "//" is a comment
  • Comments will not be run and are are used for documentation.
  • Remember to document frequently so you can refer back at a later point and understand the codes.

//Welcome to my script 
StopLoss = 10 // Crafting standardized 10 pips SL for my strategy
Identifiers
  • Identifiers are used for your variables and functions.
  • Identifiers cannot begin with a number and are case-sensitive.

//@version=4
study("PineConnector Identifiers")

IAmAnIdentifier = 25 			//having an identifier with a constant value of 25
//plot(IAmAnIdentifier) 		//since plot commented, PineScript will not execute it

FastPeriod = 20 			//storing fast MA parameter
SlowPeriod = 50 			//storing slow MA parameter

FastEMA = ema(close,FastPeriod) 	//creating and storing the fast EMA in FastEMA 
SlowEMA = ema(close,SlowPeriod) 	//creating and storing the slow EMA in SlowEMA 

plot(FastEMA, color=color.green) 	//plotting the fast MA in green
plot(SlowEMA, color=color.red)   	//plotting the slow MA in red
Strategy vs Study
  • Strategy scripts are used for backtesting.
  • This means Strategy Codes can be used to simulate buy and sell orders.

//@version=4
strategy("My Strategy", overlay=true, margin_long=100, margin_short=100)

longCondition = crossover(sma(close, 14), sma(close, 28))
if (longCondition)
    strategy.entry("My Long Entry Id", strategy.long)
  • Study are for normal script calculations but cannot be used for backtesting.
    Without the simulation of orders, less resources are used and will run faster.
    Use this, unless backtesting.

study("My Script")
plot(close)
Overlay
  • Set overlay=true if you want the plots to be on your main chart
  • Set overlay=false if you want the plots to be at a separate panel

//@version=4
study("PineConnector Super RSI", overlay=true)  //add plot to main chart
SuperRSI = rsi(close,9)				//creating Super RSI with 9 period close data
plot(SuperRSI) 					//plot SuperRSI
PineConnector
With overlay=true, the plot was added on the chart itself.
With RSI ranging between 0 and 100 and EURUSD hovering around 1.18,
the combined output means you can only see the RSI.

//@version=4
study("PineConnector Super RSI", overlay=false) //add plot to a different panel
SuperRSI = rsi(close,9)				//creating Super RSI with 9 period close data
plot(SuperRSI) 					//plot SuperRSI
PineConnector
With overlay=false, RSI has its own pane below the chart.
