Formula Screener
is the most powerful tool we provide in our service.
Whereas regular stock screener applies "and" condition to all selected criteria (i.e. all criteria must be met for a stock to be selected),
the Formula Screener allows you to combine "and", "or" and "not" conditions
to build very specific criteria.
Moreover, the Formula Screener tool gives you the possibility to combine criteria on different time periods.
Other words, it is possible to find stocks that meet some conditions on a daily chart and other conditions on weekly or monthly charts.
It worth to mention that the historical screening feature gets more flexible in the Formula Screener.
You can specify offset value for any criteria in a formula expression in days or in weeks or months if
the corresponding time periods were set for the criteria.
Range screening leverages the above approach and provides you with the ability to set a condition to be met within some period
of time. Let say you may allow moving average crossover to occur within last 3 days or require an oscillator
to be in oversold zone all time last 10 days.
Please note, that when combining many conditions in a formula, it is important to use parentheses so that the screener
knows what order to evaluate each condition.
The following examples demonstrate how to code maximally flexible criteria in formula expressions:

Output instructions

rsi(7) trend_up 5
and sortby(rsi(7), asc)

RSI(7) is trending up over the last 5 days. Stock Screener results will be sorted in ascending order by the RSI(7) indicator value.
We could also just write sortby(rsi(7)) here since the ascending order will be used by default.

The sortby function can also be used in the Strategy Backtest tool to set more flexible prioritization when adding stocks to the trading portfolio.
In this case, the criteria for opening a position should be set using a formula expression.

rsi(7) trend_dn 5
and sortby(rsi(7), desc)

RSI(7) is trending down over the last 5 days.
Stock Screener results will be sorted in descending order by the RSI(7) indicator value.

enterprise_ebitda < 15
and sortby(dvd_yield, desc, 10)

Enterprise Value to EBITDA ratio is less than 15. Stock Screener results will be sorted by dividend yield
in descending order and only the top 10 stocks will be selected.

rsi(14) ca 30
and show(rsi(14))

Find stocks for which the RSI(14) indicator crossed above 30 and add the "RSI(14)" column to the Stock Screener results page.
Columns will be added to the right of the standard columns of the stock screen and will display the corresponding values for each ticker.
The indicators listed in the show function will also be plotted on charts that are opened from the stock screen
and on mini charts when switching to the "Charts" view.

rsi(7) ca rsi(14)
and rsi(7) < 30
and show(rsi(7), rsi(14), ebitda, dvd_yield, pe)

Find stocks for which the RSI(7) line crossed above RSI(14) and RSI(7) is less than 30 and
add RSI(7), RSI(14), ebitda, dividend yield and P/E ratio columns to the Stock Screener results page.

ema(100) trend_up 100
and draw(rsi(7), rsi(14))

EMA(100) is trending up over the last 100 days.
The RSI(7) and RSI(14) indicators listed in the draw function will be plotted on charts that are opened from the Stock Screener
results page and on mini charts when switching to the "Charts" view.

Access to a trading position in the backtesting tool

price < posprice - 1

Formula expression can be used as a criteria for closing a position in the Strategy Backtest tool.
This can be done by ticking the "Extract criteria from screen" option and selecting the appropriate formula screen.
In this formula, you can get the value of the price at which the position was opened using the "posprice" literal.

In this example, we want to close a position as soon as the current price has fallen below the purchase price minus one dollar.

price cb sma(7) and price > 1.2 * posprice

In this example, we close the position when the price crosses down SMA(7), but only if the profit is already more than 20%.

price < low[posbar]

You can get the index of the day/bar on which the position was opened using the "posbar" literal.
In this example, we want to close the position as soon as the current price has fallen below the low price formed on the day the position is opened.

rsi(14) < evalat(rsi(14), posbar)

You can get the value of the indicator or expression at the moment the position was opened using the "posbar" literal and the "evalat" function.
In this example, we want to close the position as soon as the current value of the RSI(14) falls below the value of the RSI(14) recorded on the day the position was opened.

posage = 5

You can get the number of days/bars elapsed since the position was opened.
In this example, we want to close a position 5 days after it was opened.

stopat(psar(0.02,0.2))

Instructs the trading simulator to move the stop loss level to the specified value.
As a parameter, you can specify an indicator,
function, or other formula expression that returns a numerical value.
If the expression for closing a position has already been set, then the function must be added using the "or" operator.
For example: rsi(14) < 60 or stopat(psar(0.02,0.2)).
Please note that the "stopat" function is applied with a one day/bar delay. That is, stop loss is
calculated on the current day/bar but will be applied on the next day/bar.

takeat(bbub(20,2))

Instructs the trading simulator to move the take profit level to the specified value.
As a parameter, you can specify an indicator,
function, or other formula expression that returns a numerical value.
If the expression for closing a position has already been set, then the function must be added using the "or" operator.
For example: rsi(14) > 75 or takeat(bbub(20,2)).
Please note that the "takeat" function is applied with a one day/bar delay. That is, take profit is
calculated on the current day/bar but will be applied on the next day/bar.

Backtesting aids

posprice

Formula expression can be used as a criteria for closing a position in the Strategy Backtest tool.
This can be done by ticking the "Set by a formula expression" option and assigning the corresponding formula expression.

You can get the value of the price at which the position was opened using the "posprice" literal.

posbar

You can get the index of the day/bar at which the position was opened using the "posbar" literal. It is typically used in data arrays: open, high, low, close, v.
For example, low[posbar] will give the low price of the day/bar at which the position was opened.

evalat

You can get the value of the indicator or expression at the moment the position was opened using the "posbar" literal and the "evalat" function.
For example, evalat(rsi(14), posbar) will give the value of the RSI(14) indicator recorded on the day the position was opened.

posage

You can get the number of days/bars elapsed since the position was opened.

stopat(psar(0.02,0.2))

Instructs the trading simulator to move the stop loss level to the specified value. As a parameter, you can specify an indicator,
function, or other formula expression that returns a numerical value.
For example: stopat(psar(0.02,0.2)), stopat(ema(7)), stopat(lowest(21)).
If the expression for closing a position has already been set, then the function must be added using the "or" operator.
For example: rsi(14) < 60 or stopat(psar(0.02,0.2)).
Please note that the "stopat" function is applied with a one day/bar delay. That is, stop loss is
calculated on the current day/bar but will be applied on the next day/bar.

takeat(bbub(20,2))

Instructs the trading simulator to move the take profit level to the specified value. As a parameter, you can specify an indicator,
function, or other formula expression that returns a numerical value.
For example: takeat(bbub(20,2)), takeat(1.5 * ema(50)), takeat(highest(21)).
If the expression for closing a position has already been set, then the function must be added using the "or" operator.
For example: rsi(14) > 75 or takeat(bbub(20,2)).
Please note that the "takeat" function is applied with a one day/bar delay. That is, take profit is
calculated on the current day/bar but will be applied on the next day/bar.
