Support is a level where buyers overwhelm sellers, supports can come in many forms.
A support can be found at:
• Previous reaction low
• Trend lines
• Gaps
• Fibs
• Moving averages
• Ichimuku cloud bottoms
You should only buy at known supports and anywhere else is simply gambling.
This is why most traders lose, why chase a price when it can come to you under your own terms?

Once support gets penetrated it becomes resistance:
