People tend to focus on the behavior of individual investment. Then they often overreact when one of those investments goes to loss. The narrow framing tends to increase investor sensitivity to loss. As a result, this tendency implies overreaction behavior. To avoid this behavior, investors should evaluate their performance at the aggregate level with a wider frame, even accept short term losses. In FX trading, investors need to look at charts with long run time frame weekly, daily first to determine the trend. And they have to accept short term losses in the short run before the currency pair goes on the right way. The below example describes that EUR/USD daily chart is going up but 1h chart is likely to go down. That is the reason why you need to loot at wider time frames before accessing shorter frames.
