Resistances are the opposite of support levels. This is when buyers are out numbered by the sellers in the market.
This level is normally identified by a previous peak, this is the level that you should take profits.
Resistance comes in many forms:
• Previous reaction high
• Downtrend lines
• Gaps
• Fibs
• Moving averages
• Ichimuku cloud tops
Once a resistance is penetrated it normally becomes support, never buy at resistance.
