What happens to a buy market order if no one is selling?

Rule 41 Don't Be Penny-wise And Pound Foolish
When you decide to enter the market, avoid the temptation to put a price order in to get it just a bit cheaper.
This nickel-and-dime mindset will cost quarters and dollars in the long run. If you have spotted a buying formation on your stock chart and other research tells you to buy, just do it. Place a market order and get on with the next piece of analysis.

I was wondering about the risks of market orders in general and I questioning myself about what may happen in limit situations such as very limited supply.

Is the above rule a valid one?

%% Amen and seldom happens; + happens even less in a liquid market.And using a limit order to tight is worse, cause easy to have missed the move//good trend-dont quibble over a quarter+ miss the move.....

 

%% Wise words on swing position trades.Price moves good on liquid stuff, a generous limit is even better
