Check Last Closed Trade (Profit / Type / Symbol etc.) - MetaTrader 5용 expert

With this code block, you can get the last closed trade data without using loops. 

• Create a variable to set the current day start time. (This is not necessary to do.)
• Create some other variables to print a chart output and use if in other code blocks as well. (This is not necessary to do.)
• Using this code inside of the OnTick(); function leads to show result for every tick. You can set it also for once a bar. 

// variables
string DayStart = "00:00"; // Day Start Time
double LastClosed_Profit; // Last Closed trade profit
string TradeSymbol, TradeType;

you can get the whole trading history (from the very beginning of the account) by using the  HistorySelect(); function this way.

// Get entire history
HistorySelect(0,TimeCurrent());
