| The function sets a number of strategy properties | |
| Example | strategy(“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:
|
| 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 |
| 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 |
| 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 |
| 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 |
| 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. |
