Since everyone was so helpful the last time, I have one other question. I am trying to plot the Open, High, Low, Close of the previous day via the following code from MC:

variables:
	Counter( 0 ),
	YestOpen( 0 ),
	TodaysOpen( 0 ),
	YestHigh( 0 ),
	TodaysHigh( 0 ),
	YestLow( 0 ),
	TodaysLow( 0 ),
	YestClose( 0 ),
	TodaysClose( 0 ) ;
	
if Date <> Date[1] then
	begin
	{ increment Counter to be sure enough data is processed - see comment below }
	Counter = Counter + 1 ;
	YestOpen = TodaysOpen ;
	YestHigh = TodaysHigh ;
	YestLow = TodaysLow ;
	YestClose = Close[1] ;
	TodaysOpen = Open ;
	TodaysHigh = High ;
   	TodaysLow = Low ;
	end
else
	begin
	if High > TodaysHigh then
		TodaysHigh = High ;
	if Low < TodaysLow then
		TodaysLow = Low ;
	end ;

if Counter >= 2 and BarType < 3 then { if at least one full day's data has been
 processed and chart bar interval is daily, intra-day, or tick bar, then plot }
	begin
	Plot1( YestOpen, "YestOpen" ) ;
	Plot2( YestHigh, "YestHigh" ) ;
	Plot3( YestLow, "YestLow" ) ;
	Plot4( YestClose, "YestClose" ) ;
	end ;

However, in OEC (not sure if other data vendors are like this) products that trade on sunday (eg Bonds and Notes) the sunday trading is treated like an entire day. I want to use the information from friday, not sunday. I came across a pivot indicator that ignored the weekends, but when i tried to mesh that code with what I was using, I couldnt get it to compile. Once again, thanks for any help.

there are simple reserved words for this:

highd(0) = todays high
highd(1) = yesterdays high
highd(2) = high of 2 days ago

opend(0) = todays open
opend(1) = yesterdays open


etc.....

Does OEC support the ELCollections.dll

This is how I do it in Multicharts. You have a daily chart or scanner window with one indicator to save the values from the previous trading day and then another indicator reads the values on your intraday chart.

these are functions, not reserved words.

ie. someone wrote a script/"program" that perform those operations.

I admit I do not know enough about programming to know what exactly they are --- but I use Open Ecry and calling functions in the code editor on the OEC platform requires an extra step vs the seamless way EasyLanguage does it. On the OEC platform -- to the coder anyway -- there is no extra step needed so there is no effective difference between whatever they are labeled vs the label 'reserved words'. Just trying to help the original poster, not trying to argue semantics.

I did not mean to be picky. Please do not take it as a challenge. I merely wanted to clarify.


A reserved word (also called keyword) is a "command/operation" that is built-in to the program.

eg. High, print, array, text, etc.


A function is a little "program", written with the reserved words, to perform certain operation.

eg. MACD, stochastic, RSI, average, etc.



A function might, or might not be residing in your program.
If you haven't got it in your computer, you can get the code and install it.

However a reserved word is built-in to your program.
If your program haven't got that keyword, then that means your program does not support that keyword. There is no way to get that into your computer.

e.g. some of the keywords in MultiCharts are not available in tradestation or OEC.

Tams,

I am just curious -- is there a way to tell if its a keyword or a function? I mean, you do you know opend(0) is not just a keyword in the world of Open Ecry? thx in advance.

I am interested because I noted this in another thread (note that I am a programming ignoramus so I just have to figure things out without really knowing what is going on under the hood)
