Forex traders use support and resistance as point of reference for potential buy and sell entries. Therefore, if a trader sees that there is support in the AUD/USD at 1.0700, they’ll feel confident about buying just above 1.0700, since they know that other traders are buying at that level. Similarly, if one wanted to short the EUR/USD after its big move higher, selling below 1.3500 may be a good move since there has been resistance at that level s stopping previous climbs.
Overall, buying or selling along with other traders is often a winning strategy for as it increases the chances of favorable momentum. There is also risk of poor profitability when many Forex traders try to exit the same position at the same time.
