Artyom Trishkin:
This enum: enum

How do you set the timing?

int TF=PERIOD_D1;
iLowest(_Symbol, TF, 50);

And the compiler scolded me:

'TF' - cannot convert enum eMinMax_2.mq4 425 52

int TF=PERIOD_D1;
iLowest(_Symbol, TF, 50);

And the compiler scolded me:

'TF' - cannot convert enum eMinMax_2.mq4 425 52

So try

ENUM_TIMEFRAMES TF=PERIOD_D1;
iLowest(_Symbol, TF, 50);

...

Vitaly Muzichenko:

int TF=PERIOD_D1;
iLowest(_Symbol, TF, 50);

Well, the compiler scolded me:

'TF' - cannot convert enum eMinMax_2.mq4 425 52

You haven't specified in which timeseries to look for the minimum. You should

int TF=PERIOD_D1;
iLowest(_Symbol,TF,MODE_CLOSE,50);

...

[Vitaly Muzichenko]

Sergey Gritsay:

So try it.

ENUM_TIMEFRAMES TF=PERIOD_D1;
iLowest(_Symbol, TF, 50);

...

Yes, that's how it works.

Help me out here. I can't figure out the functions for working with files. I have several global variables, for example: double G; datetime M; int T; How do I write their values to a file and then extract the information back, so that the variables get their values?

Please help me to find out what colour Label is at the current time.

That is, if it is green, then BUY_= true;

Receive the same way as set, only Get

ObjectSetInteger(0,nm,OBJPROP_COLOR, clrGreen); // устанавливаем
ObjectGetInteger(0,nm,OBJPROP_COLOR,0); // получаем

Vitaly Muzichenko:

Retrieve in the same way as to install, only Get

Thank you, is this correct?

label =ObjectGetInteger(0,"MP140269",OBJPROP_COLOR,0);

if(label==Lime) BUY_ = true;

if(label==Red) BUY_ = false
