Implement a Volume Wieghted Average Price is not a difficult thing on pathfinder,

 

take a look to the formula:

as you know any variable on pathfinder become a vector so it keep trace of previous values,
this is the key that make simple this kind of implementations with pathscript, the above formula can be written as follow:

SET SUM1 = REF(SUM1 , 1) + ( OPEN * VOLUME )

SET SUM2 = REF(SUM2 , 1) + VOLUME

SET VWAP = SUM1 / SUM2

A ready to use indicator is attached for download.   VWAP

The candlestick recognition function is CANDLESTICKPATTERN() also written as CSP(),
it returns a value corrensponding to the found pattern or 0 (zero) if no patterns were found.

look at this frame of code that recognize a morning star formation:

Value_Token

set Patterns = CSP()

set STP = Morning_Star

set PTF1 = REF(Patterns,0) = Morning_Star
set PTF2 = REF(Patterns,1) = Morning_Star
set PTF3 = REF(Patterns,2) = Morning_Star

set BuySignal = PTF1 + PTF2 + PTF3

Value_Token_End

You can see how the candle paint is triggered by the same signal in three different places,
( the signal bar and two bars forward) this is for colorize not only the bar where the signal start but the complete 3 bars set.

Here is a reference to all candlestick patterns recognized by Pathfinder Trader:

An Evening start patter found on a chart…

In the attached example i will illustrate how to use this function to create a paintbar indicator that fill the three bars composing the pattern with a custom color (i will use an orange color for evening star bearish pattern and a light green for the bullish morning star).

For example, let’s program a buy condition based on a simple sma cross like this:
CROSSOVER(SMA(CLOSE, 5), SMA(CLOSE, 14))

and a specular sell condition like this:
CROSSOVER(SMA(CLOSE, 14), SMA(CLOSE, 5))

To program a buy exit that is triggered after X bars from the buy entry you can use somithing like this:
#**** SET NEEDED VARS ****#
SET BUY_NOW = CROSSOVER(SMA(CLOSE, 5), SMA(CLOSE, 14))
SET SELL_NOW = CROSSOVER(SMA(CLOSE, 14), SMA(CLOSE, 5))

SET SELL_DISTANCE = LASTIF(SELL_NOW)
SET BUY_DISTANCE = LASTIF(BUY_NOW)

SET SELL_PRICE = REF(CLOSE, SELL_DISTANCE)
SET BUY_PRICE = REF(CLOSE, BUY_DISTANCE)

#**** AND NOW THE EXIT CONDITION (REPLACE X WITH THE NUMBER OF BARS TO WAIT)****#
BUY_DISTANCE <> 0 AND BUY_DISTANCE < SELL_DISTANCE AND BUY_DISTANCE > X

As you can see this is really simple!
The LASTIF function is really usefull to keep trace of a value across the time.
