You can check those functions' return value to verify that they are successful - that will definitely remove the warnings. There is no other way to remove them. But you can still ignore those warnings as they don't impede the .ex4 generation.

how can i remove this warnings,,,,,
//-----

click on the first error or warning in the tool box error tab...... it will take you to the error or warning..... you can also see the line and column of the error to the far right in the errors tab.....

the expression has no effect means just that.... look at that line of code ...... fix what is wrong.....

the return value of orderclose should be checked warning usually has to do with the way the orders are selected..... mq4 has changed over the years.....

again, click on that warning...... it most likly will take you to a line like this.....

Code:
OrderSelect(i, SELECT_BY_POS);

try replacing that line with

Code:
if(!OrderSelect(i, SELECT_BY_POS))
//------

without seeing the code, not more help is available......h
