I just put in my first limit order, so we'll see how that goes. The thing is that they tied up my money until the order goes through or I choose to cancel.
The limit order becomes a market order when the said price is reached, only whether the filling is done or not is not guaranteed, the price is. When you place such an order your money is always going to get locked in the order. That is how it works.
My question is if you guys know of a site that doesn't do that. Like, can I put into 2 limit orders for everything and once one goes through the other is just ignored, maybe
You can look into One-Cancels-the-Other (OCO) orders, where you place two orders simultaneously and the filling of one will cancel the other automatically.
This will depend on what your exchange offers though, it may not be available on every exchange. Remember that OCO is usually used in a volatile situation and I suggest doing some dummy trading on it before heading into the actual market.
