  1. What does the language operator [] do? (Hint: It’s not for regular arrays)
    provides access to previous values of series expr1. expr2 is the number of bars back, and must be numerical. Floats will be rounded down.
  2. 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.
  3. What does the Strategy function do?
    This function sets a number of strategy properties. Examples can be: strategy(title, shorttitle, overlay and precision).
  4. What information does the Volume variable contain?
    the volume of the current bar.

Hi everyone,

  1. It enables access to the previous values of a serie. For example for a daily time frame [1] will give you the value of the previous day, [2] 2 days ago, etc…if I understood correctly.
  2. It adds an input to a script indicator.
  3. It sets a number of strategy properties.
  4. The volume associated with the current bar. You can have past values using [] as well.

  1. [ ] operator can be used to refer historical values. Historical values are variable values for the previous bars.

  2. The [input] function makes possible for script users to modify selected values from the script that can then use in its calculation or logic, without the need to modify the script’s code.

  3. A strategy is a Pine script that can send, modify and cancel buy/sell orders . Strategies allow you to perform backtesting and forwardtesting according to your algorithms.

  4. The volume Variable contains the current bar volume of trades.

Familiarizing with PINESCRIPT

With the '[ ]' operator we can retrieve previous values from our expressions i.e. previous highs or lows of our bars. We have a lot of inputs variables. If we only focus on the basic one, we can change the variables that are displayed on our script. The strategy function allows us to define all the variables that we want to introduce for a trade to take place (Currency, Slippage, trading fees, initial capital and so on). The volume variable gives us the current bar volume of the trades executed all over the world.

{ provides a value ||  series of values;}
  1. What does the input function do? (Hint: Try it in Tradingview)
    input option provides configuration options in the charts;
    oh man! i did my first try but have to add plot() into it to see on trading view what i was doing; i follow guidance from nefty.net 
study(title="Aldrin_example indicator" , overlay=false)
//input options
data = input(title="Data", type=source, defval=close)
lookback = input(title="Lookback period", type=integer, defval=20)
lenMA = input(title="Lenght MA", type=integer, defval=12)

// Calculate rate of change and its MA
roc = roc(data, lookback) 
rocMA = sma(roc, lenMA)

// Plot values
plot(series=roc, title="RoC", color=teal, style=histogram, linewidth=4)
plot(series=rocMA, title="RoC MA", color=orange, linewidth=2)

dLength = input(title="D Length", type=integer, defval=3)
obLevel = input(title="Overbought", type=integer, defval=80)
osLevel = input(title="Oversold", type=integer, defval=20)

// Compute values
stochK = stoch(close, high, low, length)
stochD = sma(stochK, dLength)

// Plot values
plot(series=stochK, color=#1E90FF, title="K")
plot(series=stochD, color=orange, title="D")

hline(price=obLevel, color=#C0C0C0)
hline(price=osLevel, color=#C0C0C0)

// Submit orders
if (crossunder(stochK, osLevel))
    strategy.entry(id="Enter Long", long=true)

if (crossover(stochK, obLevel))
    strategy.entry(id="Enter Short", long=false)
