IOC-Order is that risky?

double Bid = SymbolInfoDouble(_Symbol, SYMBOL_BID);

2019.02.25 19:46:41.976    2015.09.02 10:08:40   failed market sell 0.01 EURUSD sl: 1.12929 tp: 1.12031 [Unsupported filling mode]

I checked it via

 int FillingMode=(int)SymbolInfoInteger(_Symbol,SYMBOL_FILLING_MODE);

and it returned "2", which means:

ORDER_FILLING_IOC

This mode means that a trader agrees to execute a deal with the volume maximally available in the market within that indicated in the order. In case the the entire volume of an order cannot be filled, the available volume of it will be filled, and the remaining volume will be canceled.

Now:

Does that mean, that if I want to buy for example EURUSD for 0.01Lot, it could still be possible that the order could be executed for more than 0.01Lot?

Isnt that extremely risky and completely far away from Money management?

What else can I do if i only want to buy for 0.01Lot
