Limit order on AIM stocks

[AnilA]

Hi All. 

New to IG, so apologies for a very basic question on share dealing account. I am seeing that most of limit order expiry on most of AIM stocks has been set as Expire at the end of the day ? But for US stocks limit expiry is either day, execute & eliminate and GtC.  ? Can we amend the limit expiry on AIM stocks ?  

Also if I want to put  few Limit orders on different stocks, can the total order value be higher than the funds available i.e. put 2 limit order on A & B, each of £100 but total funds available is only £150, so if one order execute the other one automatically get cancel ? or I can only put the limit orders upto the funds available ?

Thanks in Advance.

Anil
