Basic Concept

Strategy

The function sets a number of strategy properties
Examplestrategy(“Yaonology Moving Average Tutoring”, overlay=true, default_qty_type= strategy.percent_of_equity, default_qty_value = 100, currency = currency.USD, initial_capital = 10000, commission_type = strategy.commission.percent, commission_value = 0)
Details

overlay:

true: the plot would be added as an overlay for the main series

false: the plot would be added on a separate chart pane.

default_qty_type

strategy.fixed: fixed quantity by default

strategy.cash: specified in the currency of the symbol and the amount is converted into quantity

strategy.percent_of_equity: % of currently available equity

default_qty_value

Number of contracts if strategy.fixed is used

Amount of cash in currency if strategy.cash is used

Number of percents of currency if strategy.percent_of_equity is used

currency

USD, EUR, AUD, GBP, CAD, HKD, JPY

Initial_capital

the amount of initial capital

commission_type

strategy.commission.percent: a percentage of the cash volume of order

strategy.commission.cash_per_contract: money displayed per contract

strategy.commission.cash_per_order: money displayed per order

commission_order

Number of Percentage or money, depending on the commision_type selected

Input

 

User can see and edit inputs on the Format Object dialog of the script study

Example

fst = input(title = “MA_Fast”, defval = “20”)

Details

title

title of the input


defval

default value of the input valuable

SMA

 

The sma function returns the moving average

Example

ma_fast = sma(close, fst)

Details

source(series)

close : close price

open: open price

high: highest price

lowe: lowest price


length(integer)

Number of bars

Plot

 

Plots a series of data on the chart

Example

plot(ma_fast, color = color.blue)

Details

source(series)

Series of data to be plotted


color

color of the plot.
color = color.red

color = #ff001a

color = close >= open ? color.green : color.red

Strategy.Entry

It is a command to enter market position

Example

strategy.entry(id = “ma_long”, long = true)

Details

id

A required parameter. The order identifier.


long

true: the strategy.entry for long

false: the strategy.entry for short

Strategy.Close

 

It is a command to exit from the entry with the specified ID.

Example

strategy.close(id = “ma_long”)

Details

id

A required parameter. The order identifier.
