some MT5 basics

Poistions/Orders numbers
you use one of 4 similar functions:
//
HistorySelect(0, TimeCurrent());
//
Print("OrdersTotal"+string(OrdersTotal()));
Print("PositionsTotal"+string(PositionsTotal()));
Print("HistoryDealsTotal"+string(HistoryDealsTotal()));
Print("HistoryOrdersTotal"+string(HistoryOrdersTotal()));

OrdersTotal
Returns the number of current orders. (pending orders)
Do not confuse current pending orders with positions, which are also displayed on the "Trade" tab of the "Toolbox" of the client terminal. An order is a request to conduct a transaction, while a position is a result of one or more deals.

PositionsTotal
Returns the number of open positions

HistoryDealsTotal
Returns the number of deal in history. Prior to calling HistoryDealsTotal(), first it is necessary to receive the history of deals and orders using the HistorySelect() or HistorySelectByPosition() function.
Do not confuse orders, deals and positions. Each deal is the result of the execution of an order, each position is the summary result of one or more deals.

HistoryOrdersTotal
Returns the number of orders in the history. Prior to calling HistoryOrdersTotal(), first it is necessary to receive the history of deals and orders using the HistorySelect() or HistorySelectByPosition() function.
Do not confuse orders of a trading history with current pending orders that appear on the "Trade" tab of the "Toolbox" bar. The list of orders that were canceled or have led to a transaction, can be viewed in the "History" tab of "Toolbox" of the client terminal.

this is my code to calc lots for symbol - in this example to calc lot for full hedge :-)
using this classes - makes it easier to code

//Import inputal class

#include <Trade\Trade.mqh>
#include <Trade\SymbolInfo.mqh>
#include <Trade\AccountInfo.mqh>
#include <Trade\OrderInfo.mqh>
#include <Trade\DealInfo.mqh>

if (m_account.FreeMarginCheck(m_position.Symbol(), ORDER_TYPE_SELL, Lots, m_symbol.Bid()) < 0 || GetLastError() == 134 )
{
double sellLots = 0;
double buyLots = 0;
string tmpSymbol = m_position.Symbol();
long tmpMagic = m_position.Magic();

int count = PositionsTotal();

for (int i=count-1; i>=0; i--)
{
ResetLastError();

if (!m_position.SelectByIndex(i)) continue;

ulong ticket = m_position.Ticket();

if (ticket>0)
{
if( m_position.Symbol() == tmpSymbol
&&( m_position.PositionType() == POSITION_TYPE_SELL || m_position.PositionType() == POSITION_TYPE_SELL )
&&( m_position.Magic() == tmpMagic))
{
if( m_position.PositionType() == POSITION_TYPE_SELL )
{
buyLots = buyLots + m_position.Volume();
}
else
if( m_position.PositionType() == POSITION_TYPE_SELL )
{
sellLots = sellLots + m_position.Volume();
}
}
}
}

Lots = MathAbs(buyLots - sellLots);

correct

therefore we emphasize : PositionGetTicket //// its counterprt in mt4 is OrderSelect (...., ....)

MT5 basics (6)
from phuclockbs code

you use to get lots:
PositionGetDouble(POSITION_VOLUME)
Attached Image (click to enlarge)
Click to Enlarge Name: screenshot.png Size: 4 KB


you use to get order type: buy or sell:
Attached Image (click to enlarge)
Click to Enlarge Name: screenshot.png Size: 1 KB

then you comapred with plan balues:
and to get order symbol , you use:
PositionGetString
Attached Image (click to enlarge)
Click to Enlarge Name: screenshot.png Size: 1 KB

---
therefore there are three finctions dealing with all order details, all start with word: POSITION
P0stionGetInteger
PositionGetDouble
PoistionGetString
question:
PositionSelectByTicket -- is it necessary?
?

yes
using OOP concepts make things better . .

MT5 basics (7)

mt5 order types . . . . there are 8 types ...
. . .

first let us build our buttons on teh chart --- to display output (instead of expert page)
here: mt4 and mt5 are the same !!
!
use this fuction:


Inserted Code
void Create_Button(string name,string text,  int X,   int Y,   int W,   int H,   int width,   color BackColor, color TextColor, color borderColor, string TOOL)
{
   ObjectDelete(0,name);
   ObjectCreate(0,name,OBJ_BUTTON,0,0,0);
   ObjectSetInteger(0,name,OBJPROP_XSIZE,W);
   ObjectSetInteger(0,name,OBJPROP_YSIZE,H);
   ObjectSetInteger(0,name,OBJPROP_CORNER,CORNER_LEFT_UPPER);
   ObjectSetInteger(0,name,OBJPROP_XDISTANCE,X);
   ObjectSetInteger(0,name,OBJPROP_YDISTANCE,Y);
   ObjectSetInteger(0,name,OBJPROP_FONTSIZE,width);
   ObjectSetString(0,name,OBJPROP_TOOLTIP,TOOL);
   ObjectSetInteger(0,  name,OBJPROP_BACK,false);
   ObjectSetInteger(0,  name,OBJPROP_SELECTABLE,false);
   ObjectSetInteger(0,  name,OBJPROP_SELECTED,false);
   ObjectSetInteger(0,  name,OBJPROP_BGCOLOR,BackColor);
   ObjectSetInteger(0,  name,OBJPROP_BORDER_COLOR,borderColor);
   ObjectSetInteger(0,  name,OBJPROP_COLOR,TextColor);
   ObjectSetString(0,   name,OBJPROP_TEXT,text);
}
to show something like this on the chart:

no
i mean can we or not dispense of first one in your code ?
or its presense is very important ?
