Since then learning lite-c and trying to code something useful (if i find the time through work and family). Mostly simple things like EMA crossover etc. I have no coding expirience beforehand. Currently Im curious about the japanese charts (Ichimoku indicator and Haiken Ashi bars). I managed to get the Ichimoku indicator on the charts, but failed so far to change the normal bars to Haiken Ashi Bars. In fact i just copypasted the code snippet from the help file that looks like that below, but the result ends with: 2_haiken_ashi_bar_test compiling....... Error in 'line 11: 'Close' undeclared identifier < Close[0] = (Open[0]+High[0]+Low[0]+Close[0])/4; >. And here´s the code: Code function run() { set(LOGFILE\|PLOTNOW); BarPeriod = 1; // Haiken Ashi Bars int bar(vars Open,vars High,vars Low,vars Close) { Close[0] = (Open[0]+High[0]+Low[0]+Close[0])/4; Open[0] = (Open[1]+Close[1])/2; High[0] = max(High[0],max(Open[0],Close[0])); Low[0] = min(Low[0],min(Open[0],Close[0])); return 8; } } I already tried #include <default.c>, did not work. Then i tried to declare it/them before with "vars Close = priceClose();", didnt help either. Obviously Im missing something important. I would appreciate if someone has already worked with Special Bars and could give me a hint. Thanks in advance.

In this case, it's a series of close values for the current asset. You declare it like this: Code vars Close = series(priceClose()); Did you work your way through the entire Lite-C tutorial? I highly recommend it. www.vitaltrades.com - andrew@vitaltrades.com

As i mentioned Originally Posted by M_D I already tried #include <default.c>, did not work. Then i tried to declare it/them before with "vars Close = priceClose();", didnt help either. (^here i have forget to write the series beforehand, i just noticed. but in code was correct) i thought this is clear to understand. So the code with declarations looked like this: Code function run() { set(LOGFILE\|PLOTNOW); BarPeriod = 1; vars Open = series(priceOpen()); vars High = series(priceHigh()); vars Low = series(priceLow()); vars Close = series(priceClose()); // Haiken Ashi Bars int bar(vars Open,vars High,vars Low,vars Close) { Close[0] = (Open[0]+High[0]+Low[0]+Close[0])/4; Open[0] = (Open[1]+Close[1])/2; High[0] = max(High[0],max(Open[0],Close[0])); Low[0] = min(Low[0],min(Open[0],Close[0])); return 8; } } Anyway it gives the same error, just with another error line number of course: PHP Code 2_haiken_ashi_bar_test compiling....... Error in 'line 17: 'Close' undeclared identifier < Close[0] = (Open[0]+High[0]+Low[0]+Close[0])/4; >. Last edited by M_D; 04/18/20 23:13.

Zorro will call int bar for you. That's how it changes the bar type from time-based to custom bar. That's why it's called a "user-defined bar". You (the user) are defining the bar: https://zorro-project.com/manual/en/bar.htm www.vitaltrades.com - andrew@vitaltrades.com

Code // Haiken Ashi Bars int bar(vars Open,vars High,vars Low,vars Close) { Close[0] = (Open[0]+High[0]+Low[0]+Close[0])/4; Open[0] = (Open[1]+Close[1])/2; High[0] = max(High[0],max(Open[0],Close[0])); Low[0] = min(Low[0],min(Open[0],Close[0])); return 8; } function run() { set(LOGFILE\|PLOTNOW); BarPeriod = 1; vars Open = series(priceOpen()); vars High = series(priceHigh()); vars Low = series(priceLow()); vars Close = series(priceClose()); } So means, i have to reread (again) the parts with functions in tutorial Thats a hard nut to me, to figure out where i have to put whatever to run things as i want them to. But luckily here is this forum with encouraged and helpful zorro coders like you. Thank you again, lesson learned. I really appreciate it. Kind regards M_D Last edited by M_D; 04/18/20 23:28.
