Study Backtester [MS]

May 5, 2021

Backtest your study like a strategy with our Study Backtester. Visualize your script's performance directly on the chart.

Simple to use, copy-paste a few lines of code (shown below) into your script, then set your script as input to the Study Backtester.

Visualize how your script performs against buy-and-hold over time, and get a nice print out of stats.

Settings

• Set your buy and sell signal inputs
  
• Add a stop loss
  
• Choose normal or trailing stop loss
  
• Choose the start date and time for backtesting
  
• Set trading commissions
  
• Use leverage or not
  
• Set carry cost for leveraged trades
  

Version 1

• Only supports buy-sell-buy-sell alternating signals. Any non-alternating signals will be ignored.
  
• Testing begins with 1 share of the asset at your first buy signal.
  

Things To Note

• This cannot enter or exit mid-candle. With the exception of the stop loss feature, which will calculate exits at the exact stop price.
  
• Stops are not treated as stop-orders, but as market-exists at the stop (or trailing stop) price.
  
• This DOES NOT take into account any loss of funds due to liquidation if price goes against you in a margin position.
  
• Short positions are not currently supported.
  
• Only `study` scripts are supported
  

How To Use
1) Add the following to the bottom your study's code.
//------------------------------------------------------------------------------
// FOR BACKTESTER
plot(buy ? 1 : sell ? -1 : na, title="Signals", display=display.none, editable=false)

2) Make sure `buy` and `sell` variables are assigned appropriately according to your strategy.
3) Add both your study and this script to your chart.
4) Set the "Signals Plot" setting of this script to: <your_study_name>: Signals
5) Adjust this script's settings (start date, commission, stoploss, etc) as necessary.
