SMCI has recently made a huge spike over the 4.23. The 4.23 is often a good resistance level and prices can retrace as deep as the 1.27 if they make a top there.
Trading would be much easier if not for the spike outs, but spike outs do exist.
In a spike out we should expect the strongest action of the move and it seeming impossible this won't go higher.
Spike outs of 4.23 usually have an upper range of about 25% above the resistance level. This is now met.
If we're in a spike out - an obvious rejection should come next.
