formula assistance

[stvchez]

hi,
i'm trying to write a simple formula and am getting hung up. basically, all i'm trying to achieve is:

var MACD = study.getValue(MACDStudy.MACD);

if (MACD(-1 //yesterday)) < 0 && (MACD( //current bar)) > 0

// buy

If found a good starter script which I'm trying to modify:

var MACD = study.getValue(MACDStudy.MACD);

var Signal = study.getValue(MACDStudy.SIGNAL);

if(Signal < MACD && !Strategy.isLong())

Strategy.doLong("Long", Strategy.MARKET, Strategy.NEXTBAR);

Hello stvchez,

If you're having trouble with a formula your are working with, please post it as an attachment and I'll take a look. If you are looking to have a formula built from scratch, I suggest you use the Formula Wizard. Have you tried the Wizard yet?

i have a working EFS which I'm trying to extend for what I need. here is what i have and i'll comment out the small section I'm trying to extend

var study = new MACDStudy(13,26, 9, "Close", false);



function preMain() {

setPriceStudy(false);

setColorPriceBars(true);

setDefaultPriceBarColor(Color.grey);

setStudyTitle("MACD Strategy");

setCursorLabelName("MACD", 0);

setCursorLabelName("SIGNAL", 1);

setDefaultBarFgColor(Color.blue, 0);

setDefaultBarFgColor(Color.RGB(192,75,0), 1);

}



function main() {

var MACD = study.getValue(MACDStudy.MACD);

var Signal = study.getValue(MACDStudy.SIGNAL);

if(Signal < MACD && !Strategy.isLong())

/* HERES WHERE I'M TRYING TO EXTEND.

if (MACD(-1)) < 0 && (MACD > 0)

in other words... if MACD (one bar back) is less than zero and MACD (current bar) is greater than 0, buy
*/



Strategy.doLong("Long", Strategy.MARKET, Strategy.NEXTBAR);

if(Signal > MACD && !Strategy.isShort())

Strategy.doShort("Short", Strategy.MARKET, Strategy.NEXTBAR);



if(Strategy.isLong())

setPriceBarColor(Color.blue);

else if(Strategy.isShort())

setPriceBarColor(Color.RGB(192,75,0) );



return new Array(MACD,Signal);

}

Create another variable in main() to define MACD of one bar ago
var MACD_1 = study.getValue(MACDStudy.MACD,-1);
Then you can use that variable in your conditional statement
if(Signal < MACD && !Strategy.isLong() &&
MACD_1<0 && MACD >0)
Strategy.doLong("Long", etc...)
Hope this helps
