| 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: 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 |
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 = #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 |
