I am back again. I have been working with zorro for a few months now and I was very happy with its performance.

I am currently trying to begin coding a very simple strategy that exploits the natural tendencies of gaps in price over the weekend to close. But of course I am having trouble creating the code.

I need the computer to compare the opening price on Sunday 5pm to the closing price at the prior Friday 5pm.

So looking through the manual I figure it should be something along these lines perhaps.

If (current bar's opening time is equal to 5pm EST Sunday night) then (subtract fridays 5pm EST close price) to generate a value called GAP

if abs(GAP) > some value we trade and if less than that value we do nothing

If we trade I will use this GAP value to calculate the entries, stops and limits.



I was confused about coding the first part, the comparison. Would this work:

If hour(0) = 5 and dow(0) = 7 then I would calculate a variable designated GAP like this:

GAP = OpenPrice(0) - timeOffset(ET,1,16,0)

Then I would use this GAP variable further down to decide on whether I will place a trade and how to place it.

Is this the way to code this? Any ideas or advice would be greatly appreciated.

No, the price difference from Friday 5pm to Sunday 5pm ET is calculated like this:

Thank you very much JCL.

Your help is indispensable.

Well I coded what I wanted and it is compiling but when it runs it stops at the first execution. I am not sure what is wrong.

function run()
{
set(NFA + PLOTLONG);
BarPeriod = 60;
if(dow() == SUNDAY && lhour(ET) == 5) {
int FridayBar = timeOffset(ET,SUNDAY-FRIDAY,5,0);
var PriceChange = priceOpen(0) - priceClose(FridayBar);


if (abs(PriceChange) > 19 && priceOpen(0) > priceClose(FridayBar))



enterShort();
Stop = abs(PriceChange);
TakeProfit = abs(PriceChange);

if (abs(PriceChange) > 19 && priceOpen(0) < priceClose(FridayBar))



enterLong();
Stop = abs(PriceChange);
TakeProfit = abs(PriceChange);

}





}
