when i place a buy or sell order will i go in a Queue and have a turn for example the 10001st person
or
is it luck or any kind of other formula's involved
cause i feel like a bigger amount of trade happened and mine didn't go through yet!
for instance

if i place a sell order at 65 now does it mean that 5.1365 BTC should be bought in order for it to be my turn?
Nope. Just like a normal market, if I placed my price at 65, and another person on the other hand sells his for also 65, it's up to the buyer whose item will he/she buy. There is no luck involve in here, it's just the decision of the person buying what item and whom will he/she buys.
