This is a false statement. Price in a trend most commonly continues the trend, that's how they are recognised as a trend. The least likely thing that price in a trend will do next is reverse into the opposite trend.
To be able to answer that question, we should know what you trade. Stocks, Futures, Forex, Crypto's???
While trading stocks over the last year, I've gotten caught enough time to make it a learning moment not to trust a sudden shift without first looking at a 30 days/1 hour chart from my usual 5 days/5 minutes chart. A dip that might seem significant up close may preview something far more dramatic after taking a couple steps back...
This question has been asked millions of times. Most of the people would say don't use a short time frame chart. The market moves in various manner / fashion / shape / sizes / speed .... You have to be flexible and choose the appropriate time frame chart depending on the market. sometimes you have to use < 1 min chart, sometimes > 15 min chart.
Exactly, or by looking only at the current daily activity in the chart one might be missing a hugely important support/resistance level that has been tested multiple times over the past few days/weeks. I only day trade, but if the instrument i was looking at was trading near such a level, i would want to know these levels and then trade it based on how it acts around that level, you can only find them by looking at the larger picture.
