Standard and Poor's 500 Index 8hr Chart. Solid uptrending with powerful momentum.
When looking for a long entry opportunity, we need to see a retracement to support levels either the green dotted lines and bounce or channel lines.
Traders tend to chase the market, specially when it is trending strongly as it is here. For a safer, low risk entry, it is recommended to allow price action to come to you (support levels) before attempting or considering a Long Entry.
