Theirs a couple of frame traps in the Q&A thread where someone asked for some.
A frame trap is where you leave at least 1+ frame gap in you blockstring allowing the opponent to press a button but not a big enough gap as to where their move becomes active, your second move should be active before theirs.
To find out how big of a gap your frame trap is you take the start-up of the second move and subtract the advantage on block of the 1st move and that equals how big of a gap you have. eg. Vipers ST.CL.LK is +3 on block and her CL.ST.MP has 5 frame start-up so 5-3=2, this means that your gap is 2 frames so any normal move that isn’t 2 frames is going to get counter hit if its pressed in between that gap. This is for normal moves only when you bring special moves into it it becomes a bit more complicated cause even if a move technically should get caught in the frame trap it may have properties that will allow it to escape the frame trap, eg Ryu’s MP.DP has 3 frame start up so technically it should get caught in the frame trap but it also has 4 frames of invulnerability which means you’ll get hit cause DP>Vipers MP.
Please ask any further questions in the question and answers thread instead of making a new thread, thank you
