improper enumerator cannot be used

[GrumpyDuckMan]

Hello everyone,

I'm not really understanding this error message atm.

      string LOW=DoubleToStr(MarketInfo(symbol,MODE_LOW),digits);
      string HIGH=DoubleToStr(MarketInfo(symbol,MODE_HIGH),digits);
      string OPEN=DoubleToStr(MarketInfo(symbol,MODE_OPEN),digits);  // 'MODE_OPEN' - improper enumerator cannot be used        
      string CLOSE=DoubleToStr(MarketInfo(symbol,MODE_CLOSE),digits);// 'MODE_CLOSE' - improper enumerator cannot be used

I would like to ask, how do I resolve the error?

I'm not sure of the difference between this working and the above not working.

      string LOW=DoubleToStr(MarketInfo(symbol,MODE_LOW),digits);
      string HIGH=DoubleToStr(MarketInfo(symbol,MODE_HIGH),digits);

Read the documentation. 

ID	Value	Description
MODE_LOW	1	Low day price
MODE_HIGH	2	High day price

Nothing about getting the High and Low.

iLow(

Hello friend,

so why "improper enumerator cannot be used" ?

The error makes no sense to me. I have read the documents.. the error isn't illustrated within mql4 documents.

MODE_OPEN and MODE_CLOSE are not listed here

You haven't read the documents because those enumerations do not belong to the call MarketInfo()

If you had read the documentation you would know this:
