Limit buy order when price goes above limit

I was looking into creating a limit order when price of stock would reach certain value that is above current price only to be greeted by information that it may execute immediately.

I would like to have this possibility as I think it is very useful. Why ? Imagine that you have done your research and are confident to buy a stock but only if it breaks above certain resistance/support level. Now it is not possible to do that and you need to manually buy that stock when it happens.
