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

open[1], it’ returns the open price on the previous candle.

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

The input annotation function makes it possible for script users to modify selected values, which the script can use in its calculation or logic, without the need to modify the script’s code. As an example you can set the length of the moving average in the tradingview GUI to test out different values of the MA. Specific widgets are supplied in the Settings/Inputs dialog box for each type of input

3.What does the Strategy function do?

Strategies allow you to perform backtesting (emulation of a strategy trading on historical data) . So you can determinate if your idea working or not.

4.What information does the Volume variable contain?

The traded (buy/sell) numbers of contract a per candle.

1: Series subscript. Provides access to previous values of series expr1. expr2 is the number of bars back, and must be numerical. Floats will be rounded down

2Adds 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
3:The function sets a number of strategy properties

4: Volume of current and previous bar

#84

I’d like to start off by saying that these docs are less-than-stimulating, to put it nicely.

  1. The [] allow you to access previous values of a variable
  2. input() adds input to your script indicator
  3. The strategy function allows you to set properties in your strategy
  4. Volume retrieves the… volume. Previous values can be accessed with the [] operator.
#85

Provides access to previous values of series of the numbers of bars back.

Adds an input to your script indicator e.g. bool, integer, etc.

Strategy function sets a number of strategy properties e.g. strategy.cancel , strategy.close etc.

Volume variable contains current bar volume.

3. What does the Strategy function do?

The function sets a number of strategy properties.

A few of the Strategy properties :

        * title
        * overlay
        * pyramiding
        * scale

4. What information does the Volume variable contain?

Current bar volume.

#87

Answers:

  1. Functions and operators within commands are used for common tasks that include extracting a year from a date, combining two numeric values, or testing logical conditions.

2.Input function allow us to write a script exactly the way we wanted it to be executed.

  1. Strategy functions allow us to script out entry and close position base on n== x and if > high / low [x]

  2. Volume indicator have the number of shares traded in a stock or contracts traded in futures or options. Its based on how many contracts have changed hands and from there we can determine volume data.

1. What does the language operator [] do? (Hint: It’s not for regular arrays)
This allows access to a previous reference. The reference could be a previous candle as in Fillip’s examples.

2. What does the input function do? (Hint: Try it in Tradingview)
This input function seems to get information from the given input. It is always assigned to a variable. Thus we end up getting a variable, which we can manipulate in the script, and it is the data from our input.

3. What does the Strategy function do?
This is a function which can be called to operate on and with strategy properties. (strategy._____)

4. What information does the Volume variable contain?
The volume variable is the data of the total amount (volume) traded. (This is for a given asset in a given time frame)
