File IO with ninja

[biswar]

Hi

I have created this script to manage trades once triggered by global vars with ninjatrader. Ive got this far, what id like to do is setglobal vars if and when the order is filled, Not sure how to do this part,

Also im not sure if the stplimit entries are correct for ninja. I use no strategy within ninja trader and would like it all managed by this efs, so a stop at entry is essential.

If any of you gurus out there can help and edit the attached file, it will be much appreciated.

Ninja Code..

I have worked with this tool before. I'll post all of the code I have for use with them..

This code was pulled from another system, so you'll probably have to go thru it and "glean" what you need.

File IO

Thanks Brad

i have found the problem i been having, I have used part of your script
namely this part below

The Data i get from Ninjatrader is this
"LONG",60,565.4,#2004-06-03 19:16:13#,0,#2004-06-03 19:28:25#,

The function you have below doesnt correctly read position 0, is there a better way of finding this value, Everytime it checks, it returns 0.




function CheckStateNTFile() {
var returnvalue = 0;
var f = new File("ESupdate.txt");
if(f.exists()) {
f.open("rt");
var stateline;
stateline = f.readln();
f.close();
var PosCount = stateline.split(",");

if (PosCount[0] == "FLAT") {
returnvalue = 0;
StrategyisInTrade = false;
StrategyisShort = false;
StrategyisLong = false;
} else if (PosCount[0] == "PENDING") {
returnvalue = 2;
} else if (PosCount[0] == "LONG") {
returnvalue = 1;
StrategyisInTrade = true;
StrategyisShort = false;
StrategyisLong = true;
} else if (PosCount[0] == "SHORT") {
returnvalue = -1;
StrategyisInTrade = true;
StrategyisShort = true;
StrategyisLong = false;
}
} else {
returnvalue = 0;
}
debugPrintln("NT Status :"+returnvalue);
return (returnvalue);
}

Did you ever figure this out? I am trying to do the same thing and seem at a loss for getting these file checks performed properly?

yep got there in the end have a script up and running working fine
this modified code works below


function CheckStateNTFile() {
var returnvalue = 0;
var f = new File("ER2update.txt");


if(f.exists()) {
f.open("rt");
var stateline;
stateline = f.readln();
f.close();
if (stateline != null){
var PosCount = stateline.split(",");

var s = PosCount[0];

var position = s.substr(1,4);
//debugPrintln(position);
if (position == "FLAT") {
returnvalue = "50";
StrategyisInTrade = false;
StrategyisShort = false;
StrategyisLong = false;

} else if (position == "0") {
returnvalue = "2";
} else if (position == "LONG") {
returnvalue = "1";
islong = "True";
StrategyisInTrade = true;
StrategyisShort = false;
StrategyisLong = true;
contractson = new Number(PosCount[1]);
fillprice = new Number(PosCount[2]);
} else if (position == "SHOR") {
returnvalue = -"1";
isshort = "True"
StrategyisInTrade = true;
StrategyisShort = true;
StrategyisLong = false;
fillprice = new Number(PosCount[2]);
}
} else {
returnvalue = 0;
}
debugPrintln("NT Status :"+returnvalue);
return (returnvalue);

}
}
}
