  1. What does the language operator [] do? (Hint: It’s not for regular arrays)

You may use arithmetic operators with numbers as well as with series variables. In case of usage with series the operators are applied elementwise.

  1. What does the input function do? (Hint: Try it in Tradingview)

Adds an input to your 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.

Value of input variable.

ARGUMENTS

defval (Its type must match the type defined with the ‘type’ parameter’s value) Determines the default value of the input variable proposed in the script’s “Settings/Inputs” tab, from where the user can change it. When used with the input.time type, the value can be a timestampfunction, but only if it uses a date argument in const string format.

title (const string) Title of the input. If not specified, the variable name is used as the input’s title. If the title is specified, but it is empty, the name will be an empty string

type (const string) Input type. Possible values are input.bool, input.integer, input.float, input.string, input.symbol, [input.resolution]

minval (const integer, float) Minimal possible value of the input variable. This argument is used only when input type is input.integer or input.float.

maxval (const integer, float) Maximum possible value of the input variable. This argument is used only when input type is input.integer or input.float.

confirm (const bool) If true, then user will be asked to confirm input value before indicator is added to chart. Default value is false. This argument not used when input type is input.source.

step (const integer, float) Step value to use for incrementing/decrementing input from format dialog. Default value is 1. This argument is used only for input types input.integer and input.float.

options (List of constants: […]) A list of options to choose from. This argument is used only for input types input.integer, input.floatand input.string.

tooltip (const string) The string that will be shown to the user when hovering over the tooltip icon.

inline (const string) Combines all the input calls using the same argument in one line. The string used as an argument is not displayed. It is only used to identify inputs belonging to the same line.

group (const string) Creates a header above all inputs using the same group argument string. The string is also used as the header’s text.

REMARKS

Result of input function always should be assigned to a variable, see examples abo

  1. What does the Strategy function do?

The function sets a number of strategy properties.

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

  1. What information does the Volume variable contain?

TYPE

series[float]

REMARKS

Previous values may be accessed with square brackets operator [], e.g. volume[1], volume[2].

“Script inputs look and behave exactly the same as inputs of built-in Technical Analysis indicators.”

  1. The strategy function lets us set a variety of strategy parameters.
    Some basic functionality includes strategy.entry and strategy.close.

  2. The volume variable contains the volume for the current bar. It can be used in conjunction with [n], where n is a positive integer, to find the volume of previous bars.

  1. [] in pine-script is called History Referencing Operator . With that, it is possible to refer to the historical values of any variable of a series type (values which the variable had on the previous bars). So, for example, close[1] returns yesterday’s close price -which is also a series.

  2. The input () function returns the current value of the input option. This value always needs to be assigned to a variable

  3. A strategy is a Pine script that can send, modify and cancel buy/sell orders. … When you write a strategy , it must start with the strategy annotation call (instead of study ). Strategies may plot data, but they can also place, modify and cancel orders.
