### [PL] Daily"ohlc"

Dear All,

How can you ask powerlanguage to give you the highest high, lowest low, open and close of the previous day?

dailyhigh(0), dailylow(0) etc. do not seem to work.

I am trying to programme trendlines for pivot points..

Many thanks,

Take a look at the functions OpenD, HighD, LowD and CloseD if you are using intraday data. That is what they do. Or, you can write something that does this by simply watching when date <> date[1] and keeping track of it in a few lines of code (see how the functions above work for an example of how.)

Dear Bruce,

Thank you for your reply. This is what I was looking for.

I use the following to calculate the pivot point:

Code: Select all

`var0 = ( HighD( 1 ) + LowD( 1 ) + CloseD( 1 ) ) / 3;plot1( var0, "Pivot Point" );`

But var0 returns 1 and sends the candlesticks high up the window.

Is there anything wrong in this code?

Many thanks,

Bruce DeVault

Perhaps you are referring to the fact that the functions return -1 when on the first date, and thus there isn't any previous date's information to return. The average of three numbers all of which are -1 is still -1. You simply need to check for this.

Code: Select all

`variables: var0(0);var0 = ( HighD( 1 ) + LowD( 1 ) + CloseD( 1 ) ) / 3; if var0 > 0 then plot1( var0, "Pivot Point" ); `

Dear Bruce,

Unfortunately, nothing it displayed at all when I use your suggestion, it is like var0 is never greater than 0.

I wonder why...

Do you have more than one day of data on your chart? It will have a value after the first day of data.

Thank you TJ, this is just awesome!

There is much for me to learn in there.
