How do I add minutes to the advisor's block of hours?

//input parametrs
input uchar                InpStartHour            = 1;           // Start hour
input uchar                InpEndHour              = 23;           // End hour

//---------------------------

void OnTick()
  { 
   MqlDateTime STimeCurrent;
   TimeToStruct(TimeCurrent(),STimeCurrent);
  
   if(STimeCurrent.hour<InpStartHour || STimeCurrent.hour>InpEndHour)
      return;
   }

How do I add minutes to the hourly block of an EA?

High Low Strategy On Time 2:

The bool TimeControl() is a function responsible for checking the time. It can work in two states: both dates within a day or dates over a day.

//--- input parameters
***
input bool     InpTimeControl       = true;        // Use time control
input uchar    InpStartHour         = 10;          // Start Hour 
input uchar    InpStartMinute       = 01;          // Start Minute 
input uchar    InpEndHour           = 15;          // End Hour 
input uchar    InpEndMinute         = 02;          // End Minute

Please advise,

In MQL5 I need to close half of a position, but I need to check if half of the position is less than the minimum lot and then close the whole volume, is that correct?

double volume=MathMax(PositionGetDouble(POSITION_VOLUME)/2,SymbolInfoDouble(_Symbol,SYMBOL_VOLUME_MIN)/AccountInfoInteger(ACCOUNT_LEVERAGE));

Maybe it is easier to check before dividing, if the lot is less than 2x the minimum, then there is no need to bother the terminal?

I can't pass the test for the marketplace, it returns an error, but there is no error in the report

What to do?

How do I get the closing price of an order (trade, position - anything at all)?

For orders, only ORDER_PRICE_OPEN is available, but ORDER_PRICE_CLOSE is not.

The positions have only POSITION_PRICE_OPEN.

The trades don't have anything abstract at all: DEAL_PRICE.

Googled the forum, didn't find it.

To make understanding and working in MQL5 easier:

1. ***

2. If you need a closing price, you cannot do without accessing the trading history. TheHistorySelect is responsible for requesting the trading history

3. The example of working with the history, with output of information either in a file or in the "Experts" tab, is in theHistory Deals and Orders code

To understand what deal this is, you need to know

ENUM_DEAL_ENTRY-direction of the deal - entry into the market, exit from the market or reversal

ENUM_DEAL_ENTRY

Identifier	Description
DEAL_ENTRY_IN	Entry into market
DEAL_ENTRY_OUT	Market exit
DEAL_ENTRY_INOUT	U-turn
DEAL_ENTRY_OUT_BY	Close counter position

ENUM_DEAL_TYPE-Type of deal

ENUM_DEAL_TYPE

Identifier	Description
DEAL_TYPE_BUY	Buy
DEAL_TYPE_SELL	Sell
***

These are the basics.

Thanks for the reply, I've looked at both the documentation and your example, but still haven't found how to get a parameter similar to OrderClosePrice() in MT4.

alternatively openhttps://www.mql5.com/ru/code/16006

and look at@fxsaber's implementation

or just connect the above library and transfer the code from MT4 to MT5, in 99% of cases you won't have to tweak anything, everything will work the same as in MT4
