  1. Language operators are constructs defined within programming languages which behave generally like functions. They can include addition, subtraction, division etc. The language operator can define or add new meaning.

  2. The input function input( ) allow us to quickly alter script values by manually changing an input option (like the RSI overbought level). That way we can change the values used in the script without having to edit its source code.

  3. In Pine Script, the strategy.entry() function is a command to open a long or short trade (TradingView, n.d.). This function is quite flexible. It can open new positions, scale into an existing position, and reverse a position in the other direction.

  4. Volume Profile takes the total volume traded at a specific price level during the specified time period and divides the total volume into either buy volume or sell volume and then makes that information easily visible to the trader.

1. What does the language operator [] do?
The [] is a numerical operator that lets you go back and access values from previous candles. You define the number of bars / candle sticks on the chart you want to access data from or refer to by adding a number inside the bracket, e.g. [0] refers to current day candle; [1] refers to yesterday’s or previous candle; [2] refers to the day before last; etc.

2. What does the input function do?
Data Input: It adds an input to the script indicator, e.g. technical analysis indicators to your program. It also allows you to change values in your script.

3. What does the Strategy function do?
The strategy function allows you to define specific parameters and properties of your trading setup, such as conditions for market entry/exit/close, order or cancel, stop loss or taking profit, etc. so that the program can execute code in the trading environment. You can also simulate trades using this function, based on your trading algorithm.

4 most common functions for entering/exiting a market position:
strategy.close
It is a command to exit from the entry with the specified ID. If there were multiple entry orders with the same ID, all of them are exited at once. If there are no open entries with the specified ID by the moment the command is triggered, the command will not come into effect. The command uses market
strategy.entry
It is a command to enter market position. If an order with the same ID is already pending, it is possible to modify the order. If there is no order with the specified ID, a new order is placed. Every entry is closed by a separate market order.
strategy.exit
It is a command to exit either a specific entry, or whole market position. If an order with the same ID is already pending, it is possible to modify the order. If an entry order was not filled, but an exit order is generated, the exit order will wait till entry order is filled and then the exit order is placed.
strategy.order
It is a command to place order. If an order with the same ID is already pending, it is possible to modify the order. If there is no order with the specified ID, a new order is placed.

4. What information does the Volume variable contain?
It feeds your program with data on the current bar’s (buy/sell) volume level, or how much of an asset was traded during a given period. Not only current value of trade volume bars, but also previous bars/values can be accessed by indexing using square brackets operator: volume [1], volume [2], etc.

  1. [] can be used to “save” variable value between bars

  2. The input function looks and behaves exactly like built-in inputs of any Technical analysis indicators.

  3. It sets a number of strategy properties. “title” “scale” “open” “close”

  4. The current bar volume.
