  1. Provides access to previous values of series X. Y is the number of bars back, and must be numerical. Example: X[Y] contains a value of Y bars backwards.

2…Adds an input to script indicator. User can see and edit inputs on the Format Object dialog of the script study. Script inputs look and behave exactly the same as inputs of built-in Technical Analysis indicators.

  1. Strategy function sets a number of strategy properties. Every strategy script must have one strategy call.

  2. Volume variable contain current bar volume.

  1. [] lets you query past instances of a variable… example if you wanted to confirm current candle open is greater than previous candle open: open > open[1]
  2. The input function provides an interface so you can edit the variable value via script settings. It also allows you to set the default, minimum and maximum allowed value where applicable.
  3. The strategy function emulates entering and exiting positions for back testing.
  4. Volume variable contains the buy/sell volume for the current bar.

1. What does the language operator [] do? (Hint: It’s not for regular arrays)
This is the series subscript.
It provides access to previous values of series expr1. expr2 is the number of bars (candles) back. It must be numerical and floats will be rounded down.

2. What does the input function do? (Hint: Try it in Tradingview)
It allows the user to see and edit inputs on the Format Object dialog of the script study. What this means is you add the script to your chart and you can therefore change specified variables or settings in the chart values without having to go into the source code.

3. What does the Strategy function do?
It sets a number of strategy properties which are all listed and defined in the reference manual. The only argument that is required is title(const string), others are optional or a default is applied.
Every strategy script must have one strategy call.
Here is the list

strategy(title, shorttitle, overlay, format, precision, scale, pyramiding, calc_on_order_fills, calc_on_every_tick, max_bars_back, backtest_fill_limits_assumption, default_qty_type, default_qty_value, initial_capital, currency, max_lines_count, max_labels_count, slippage, commission_type, commission_value, process_orders_on_close, close_entries_rule) → void

4. What information does the Volume variable contain?
The current bar volumes, ie the buy/sell.

  1. What does the language operator [] do? (Hint: It’s not for regular arrays)
  • Called the Series Subscript, it provides access to previous values.
  • close [ 1 ] will give the close value of the candle before the current (current would be [ 0 ], but that can be omitted).
  1. What does the input function do? (Hint: Try it in Tradingview)
  • It allows to define inputs to the strategy.
  • For example, this:
b = input(title="On/Off", type=input.bool, defval=true)
plot(b ? open : na)

gives a simple on/off switch to a graph:

  1. What does the Strategy function do?
  • It sets different strategy properties, such as title, precision, scale, to the strategy that we define further in strategy.entry(), strategy.close() and other statements.
  1. What information does the Volume variable contain?
  • The trading volume of the current bar.
  • So it would be reset to 0 at the beginning of each candle and then go up and up until the next candle…?

  1. This operator can take an index. Starting from one every index is a previous candle (1 is previous, 2 is the one before an so on)
  2. The input function allow the user to change a function variable interactivilly. Can take a default value a max and a min value
  3. Strategy can be used to set properties, like when to open or close a strategy etc.
  4. Volume contains the volume of the current candle (or the corresponding candle if used with [] operator)

1.The language operator[] is used as a subscript, which can call on values inside of the series it is the subscript of. Using numbers inside of a subscript bracket, you can reference previous candles on a chart. Putting a zero in the chart while putting a one would reference yesterdays and a two would reference the day the day before yesterday before yesterday and so on…
2. Input functions add an input to your script indicator. The user can see and edit inputs on the format object dialogue of the script study. Also, script inputs look and behave exactly the same as inputs of built in TA indicators.
3. Allows you to backtest a idea you have created in the pine script or backtest a pre loaded template.
4. It contains the current value of trade volume bars and previous volume bars. Implementing the information or value using the square bars.
