Help me, verification of past trades

[rafael_roloff]

Greetings everyone, I'm new to the language MQL4, and would help to make two checks, if they can help me, how I could do these checks, follows:

checking if the last trade has been lost or not.
check which was the lot of the last volume of trade.

Could someone help me?

Greetings

}

   For large amounts of code, attach it

2. What are Function return values ? How do I use them ? - MQL4 forum
3. Loops and Closing or Deleting Orders - MQL4 forum
4. You already posted lastlot(). What is your problem with coding an equivalent using OrderProfit()

When I opened the topic I still do not know this code, but I ended up finding another expert in the code, if someone posted here let also search by subject.

Thank you for your attention.
