Hi,
I was going over a system that I downloaded and could not find the definition of "&& " and the 2 vertical lines, || which I cant even find on my keyboard..They are
separating the 2 sell rules.

Could you either explain them or refer me to documentation..

Thanks,

Allan

buy = rule1 and (close * sma(volume, 10) > 50000 and close > 2) && ((perf(close, 35)) > (4)) && ((volume) > (1 * sma(volume, 5))) && ((perf(close, 10)) < (8));
sell = ((absolute((close / sma(close, 10)) - 1)) < (0.04)) || ((perf(close, 35) / perf(close, 5)) > (1.02));

Best Answer

Hi Allan,

&& means AND
|| means OR

You can either use && or AND and || or OR

Example:

buy = close > 10 && volume > 100000;

buy = close > 10 and volume > 100000;
