Welcome

Yes, momentum trading is purely based on small yet significant price action. The momentum may either be with the trend or against the trend. A momentum against the trend may lead to trend reversal. Trend traders can use momentum trading strategy as their entry strategy.
On the other hand classical trend trading is based on support & resistance levels, where the focus is on the direction of the price action and not the momentum.
Momentum strategy is multi purpose in nature and can be used as...
1. Entry strategy for an existing trend strategy.
2. Entry strategy for an existing reverse trend strategy.
3. Signal for existing trend or reverse trend if price wont crossover within 60 minutes.
4. Scalping point.
5. Stay away zone for range bound trading.
