Questions..

Hi everyone,

First of all, I'm still learning the MQL4 language(newbie here only at lesson 2), and I'm not really a programmer. I just have several questions:

1.How do you determine the high and low of a candlestick and everything in between? Like, I want to know if a certain value has been included in the candlestick.


2.Is it possible to get the value of an indicator? like alligator, zigzag, etc

Indicator value

3.How do I get value of previous candles, like 1hr or 30min ago?

Thank you everyone!!!

 

https://docs.mql4.com/indicators/icustom

double iCustom( string symbol, int timeframe, string name, ..., int mode, int shift)

 

mode = buffers, shift = bar number beginning with bar zero (0)

on a related note anyone; how do you use the stoch levels???

without indicators using HLCO and what bar like double f = Close[1];

1.  If you want to know if during a tick that made up that candle was bid price at x.x ,  you can't,  MT4 holds the following data for each bar, OHLC datetime and volume (tick count).  If you want to know if a particular bar covers a certain price . . . test if the price in question lower than the Bar's High and higher than the Bar's low

2.  Yes,  use iCustom . . .  use the Search in the top right corner of this page

3.   You can use functions like iHigh(), iLow(), iOpen() & iClose() to get bar values for other timeframes . . . the currently forming bar is bar 0,  one to the left is 1, then 2, etc   is that what you meant ?

 

1.How do you determine the high and low of a candlestick and everything in between?
High[] || iHigh(), Low[] || iLow(), Open[] || iOpen, Close[] || iClose.

Like, I want to know if a certain value has been included in the candlestick.
if( Certain_Value<=iHigh() && Certain_Value>=iLow() ){ bool Included=true; }

2.Is it possible to get the value of an indicator? like alligator, zigzag, etc
Yes, use iCustom() and find_values Example. https://www.mql5.com/en/forum/131897

      while(found<4){
         if(iCustom(Symbol(),period,"ZigZag",12,5,3,0,i)!=0){
            swing.value[found]=iCustom(Symbol(),period,"ZigZag",12,5,3,0,i);
            swing.date[found]=iTime(Symbol(),period,i);
            found++;
         }
         i++;
      }

3.How do I get value of previous candles, like 1hr or 30min ago?
Again: High[] || iHigh(), Low[] || iLow(), Open[] || iOpen, Close[] || iClose.
Examples:
iHigh(Symbol(),Period_H1,1) //<--High of Last H1 Bar.
iLow(Symbol(),Period_M1,29) //<--Low of the 30th Minute Bar.
iLow(Symbol(),Period_M30,1) //<--Low of the Last M30 Bar.

iRSI(Symbol(),Period_H1,14,PRICE_CLOSE,0)
iCustom(Symbol(), Period, "SampleInd",13,1,0);

Wow, thanks everyone, ubzen, I'll try your examples, I'll update you. Thanks a bunch!!!
 
Everything works great, just one more question though, how do I call the last peak of an indicator, like in zigzag?

I'm no expert on this indicator. However, my thinking is that you take the highest value of the last two swing_locations found. Ps- From what I've read on this forum & else-where, be careful with this indicators [ current | last ] swing because it changes it's [ mind | repaints ]. Also, when observing this indicator, the swings you're seeing historically usually isn't what it was in real-time.

 
No worries, I may have a solution for that, but still working on it :)
