String Parsing Question

[dloomis]

var symbol=getSymbol();

might return

"NQ Z2=2"

How can I get "NQ Z2=2" to turn into "NQ" ?

[dsnyc]

Try symbol.substring(0,2). This will return the first two chars of the symbol string.

Hi David,

If your chart is NQ2=2, do you really want to use just NQ for your study?

In any case, Java Script does have all KINDS of string manipulation look HERE for some of them.

You could use slice() if you know that the symbol stays a fixed format (or even scan for a pattern, and then let that determine the paramters to slice().

You could also use split().

For that matterm you could great a loop from zero to string.length
and copy from the ParseString[i] to the TargetString[i] up to the point you see your separator.

Just a few ideas...

NQ is needed for the order entry strings I am developing.

function main()

debugPrintln (sym);

Cool. If you have a few seconds and are willing to share - what is it you are trying to do with broker order entry (ie: autofire orders, populate an order entry window, intergrate to some 3rd party tool).

dloomis,

We're about to publish several EFS functions tonight that help to convert eSignal names into one needed by Dynaorder's Order Execution functions.

So you'll be able to do this:

var symbolName;
var symbolType;
var symbolExpiry;

symbolName = doGetName(getSymbol()); // will return "ES" for "ES Z2"

symbolType = doGetType(getSymbol()); // will return "FUT" for "ES Z2" and "STK" for "MSFT"

symbolExpiry = doGetExpiry(getSymbol()); // wil return "200212" for ES Z2 and "" for MSFT.

Check our Web for the functions source code tonight.

DB,

Where are your new efs studies posted?

[dynastore]

They not ready yet.
They should be ready by tomorrow (Friday) morning at this page:

http://www.dynaorder.com/efs-examples.asp

Sorry for the delay,
DB

OK, the EFS and explanation are here:

auto trading paper trading

I just uploaded my papertrader efs file. This script requires reloading to work.

The purpose is to issue an order, wait for the fill, then issue two stop limit orders.

Right now the order fires, fills and then about 30 secs later the stop loss order fires away. Sometimes it doesnt fire at all.

Any suggestions welcome.

Try not to make fun of my programming skills, I am trying to learn.

Hey dloomis,

Not sure if I am the perfect person for this since I don't use dynaloader, but I will take a peek at it. I did a search (using the very nice new search ability) in the fileshare for this and couldn't find it. Mind giving me the URL to where you uploaded it?

Hi,

I looked at it, and all looks fine. I read up on the Dynaloader papertrader and also looked at other posted examples, and nothing in your code leapt out at me.

Perhaps the good people at Dynaloader could comment.

BTW, the Dynaloader stuff look very cool, and failry full featured. Glad I was given an excuse to read up on it.
