Placing Automated Orders with URLS

[Chris747]

Hi there folks,
I have the capability to place orders automatically to my dealer using URL's. If my EFS script determines that it's time to place an order...I can do so using something that looks like...

if (isLastBarOnChart( )){

//now place order to dealing station

@URL=http:://dealer.com/services/auto.asmx/[email protected]&PWD=chris&Pa ir=GBP/USD&BuySell=B&Amount=200000

}

I've been messing with this for awhile without much success. The problem seems to be illegal charachters...and I'm not sure which one nor how to "escape" them. Characters in question are "&", "?" and perhaps the "/".

Next question is in calling it...Would i just use @URL=http://...etc. as I'm doing?

Thanks !

Hello Chris,

I have an idea for this. But it won't be an automated trading process. Basically, what you need to do is draw a button that uses your URL. When you get a signal from your strategy, you would have to click on the buy sell buttons, which launches a browser with your specified URL string.

The URL needs to be created as a string which would be built with the necessary parameters for buy/sell, price etc., within your strategy at the same instance that your signals occur. But only if you have parameters such as price that need to be changed in the URL string. If you just need market buy/sell buttons you won't need to redraw the buttons. If you do need to redraw the buttons all you need to do is set your global variables for price or type to the appropriate values and then call drawButtons(). Let me know if you need more help with this.

Here's a basic code example to get you started.

ChrisTradeButtons.efs

function preMain() {
    setStudyTitle("Trade Buttons ");
    setPriceStudy(true);
    setShowCursorLabel(false);
    
    var dp1 = new FunctionParameter("Size", FunctionParameter.NUMBER);
    dp1.setName("Lot Size");
    dp1.setLowerLimit(1);
    dp1.setDefault(100);    
}

var bEdit = true;
var vSize = 100;
var vBaseURL = ("http://dealer.com/services/auto.asmx/" + 
              "[email protected]" +
              "&PWD=chris&Pair=GBP/");
var sBuyURL = (vBaseURL + "USD&BuySell=B&Amount=" + vSize);
var sSellURL = (vBaseURL + "USD&BuySell=S&Amount=" + vSize);

function main(Size) {
    if (bEdit == true) {
        if (Size != null) vSize = Size;
        drawButtons();
        bEdit = false;
    }
    
    // add your strategy code here
    
    return;
}

function drawButtons() {
    drawTextAbsolute(5, 49, " Buy @URL="+sBuyURL, Color.white, Color.green, 
        Text.RELATIVETOLEFT|Text.RELATIVETOBOTTOM|Text.FRAME|Text.ONTOP|Text.BOLD|Text.CENTER, 
        "Arial", 12, "Buy");
    drawTextAbsolute(5, 29, " Sell @URL="+sSellURL, Color.white, Color.red, 
        Text.RELATIVETOLEFT|Text.RELATIVETOBOTTOM|Text.FRAME|Text.ONTOP|Text.BOLD|Text.CENTER, 
        "Arial", 12, "Sell");
        
    return;
}
