Range screening

(rsi(14) ca 80)@[0..4]

RSI(14) indicator crossed above 80 within the last 5 days/bars. This formula is equivalent to
(rsi(14) ca 80)@0
or (rsi(14) ca 80)@1
or (rsi(14) ca 80)@2
or (rsi(14) ca 80)@3
or (rsi(14) ca 80)@4
Note that in this example, we used square brackets.

(rsi(14) > 80)@{0..4}

RSI(14) indicator is above 80 during the last 5 days/bars. This formula is equivalent to
(rsi(14) > 80)@0
and (rsi(14) > 80)@1
and (rsi(14) > 80)@2
and (rsi(14) > 80)@3
and (rsi(14) > 80)@4
Note that in this example, we used curly brackets.

( rsi(14)@fixed > rsi(14 )@1)@{0..9}

RSI(14) indicator has reached its maximum value in the last ten days.
This formula is equivalent to rsi(14) > rsi(14)@1 and rsi(14) > rsi(14)@2 and .. and rsi(14) > rsi(14)@10. Note that in this example, we used curly brackets.
Range shifts are not applied to a @fixed expression, allowing it to have a fixed value. As if we can build loops, leaving some expressions inside the loop unchanged.

( close[0]@fixed > close[1] )@[0..9]

Today's closing price is higher than the closing price of at least one of the last ten days.
This formula is equivalent to close[0] > close[1] or close[0] > close[2] or .. or close[0] > close[10]. Note that in this example, we used square brackets.

Using data arrays

high[1] > high[2]
and low[1] > low[2]
and v[1] > 2 * v[2]
and close[0] > high[1]
and open[0] > low[1]

The previous bar shows ascending high and low with doubling volume
and the current price is greater than the previous high
and the open price is greater than the previous low
Note that the following abbreviations can be used to indicate the current values of open, high, low, and close prices:
open = o, high = h, low = l, close = c = last = price

low[0] > 1.05 * high[1]
and close[0] > 1.05 * open[0]

Gap up is greater than 5%
and change from open is greater than 5%

v[0] > 1 and open[0] > close[1] + 10

Today's volume is greater than 1 million and open price is greater than previous close + $10

Volume

avol(10) > 1
and advol(10) > 100

10day average daily volume is greater than 1 million and 10day average daily dollar volume is greater than 100 million
We use avol and advol with parameters in this example. If the parameter is not specified, then they use the period of 21. It is worth noting that this period corresponds to one calendar month since there are usually 21 trading days in one month.
avol and advol used without parameters in the previous examples are equivalent to avol(21) and advol(21) correspondingly.

( v[0] > 3 * avol(10)
or v[1] > 3 * avol(10) )
and (v[0] + v[1]) > 5 * avol(10)

Today's or yesterday's volume is at least three times greater than the 10day average daily volume, and today's and yesterday's volume, in sum, is at least five times greater than the 10day average daily volume average.

volume trend_up 7 and vma(21) trend_up 7

The volume has been trending up over the last seven days, and the volume 21day moving average has been trending up over the last seven days

rvol > 5

Relative volume is greater than five. Relative volume is calculated as the ratio of the current daily volume to the 21day average daily volume. You can also use rvol with a parameter. For example, rvol(10) > 5 expression reads as the ratio of the current daily volume to the 10day average daily volume is greater than five.

Aggregate functions

price > max( h, 10 )@1

The current price is higher than the maximum value of high prices calculated for the last 10 days at the time of yesterday.

price < min( l, 10 )@1

The current price is lower than the minimum value of low prices calculated for the last 10 days at the time of yesterday.

max( ema(200), 10 ) 
min( ema(200), 10 )
< .02 * price

The difference between the maximum and minimum value of the EMA indicator for the last 10 days is less than 2% of the price.

avg( rsi(14), 10 ) > 80

The average value of the RSI indicator for the last 10 days is above 80.

abs( rsi(14)  50 ) > 40

The absolute value of the difference between the value of the RSI indicator and 50 is greater than 40.

Scoring conditions

(price trend_up 21)
+ (price risunvol)
+ (price higher_highs 7) >= 2

At least two of the three conditions in the expression must be met.
Note that each condition in the expression is converted to 0 or 1, depending on whether it is met or not.

(rsi(14) div_bull)
+ (ao(5,34) div_bull)
+ (cci(14) div_bull)
+ (mom(14) div_bull)
+ (stoch(5,3,3) div_bull)
>= 4

At least four of the five conditions in the expression must be met.

Conditional expressions

rsi(14) ca if(price > ema(21), 60, 40)

This formula expression will work like rsi(14) ca 60 in case if price > ema(21) and as rsi(14) ca 40 otherwise.
It is worth noting that this expression is a shorter form for (price > ema(21) and rsi(14) ca 60) or (price <= ema(21) and rsi(14) ca 40).

Output instructions

rsi(7) trend_up 5

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

ema(100) trend_up 100
and draw(rsi(7), rsi(14)) 
EMA(100) is trending up over the last 100 days.

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%.
You can also get access to the position's stop loss and take profit by using the posstop and postake variables correspondingly.

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.

if(price > 1.05 * posprice, stopat(low[0])) 
The IF function can be useful in the formula for closing a position in combination with the STOPAT or TAKEAT instructions.
In this formula, the stop loss will be set at the day's low level, but only if the position's profit is more than 5%.
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 if(price > 1.05 * posprice, stopat(low[0]))
