Currency prices in the forex markets are always jumping up and down. Forex markets are volatile most of the time. In the short term, you will only find noise in the intra day forex market. This makes it difficult for new day traders to know how to put a stop loss. Most of the time, prices in forex markets jump 10-20 pips for no apparent reason.
This becomes frustrating for many new day traders. Most constantly find their stop losses being tripped due to noise even when the rates are going in the anticipated direction.
A static 10-20 pip stop loss is an arbitrary choice many traders make. Many new traders also use Trailing Stop Loss. Place your trailing stop loss too close and you will find your stop hit too early. Place it too far and you will have to forgo potential profits if the price retraces.
The actual reality is this that many professional forex traders do use stop loss but mostly place it on their computers making it invisible from their brokers. A better method to place a stop loss is by using a dynamic level that changes as the market rate changes.
Stop hunting is something the brokers are continuously doing. If a broker finds many stop losses at a particular price level on his price feed; he can easily trip them using a momentary blip in the price. You cant even complain. The momentary spike happened due to a sudden large transaction in the market.
More often than not, professional traders, trade with a stop loss at all, only keeping a mental stop loss. But you will need a lot of experience to trade this way.
Using dynamic stop losses such as Moving Averages, Bollinger Bands, SARs etc is a better way to reduce your risk while allowing the markets to do what it wants.
With more experience, you will learn that placing fixed stop losses actually harms more. Rather than helping, using a fixed stop loss can hurt you more emotionally, psychologically and profit wise.
You should not try to trade before or after a major economic news release. You should not try to place stop loss close to or at round numbers. And you should also not try to trade in times of thin liquidity in the currency markets.
It is important for you to know that brokers constantly use stop hunting to take out your positions using noise in the market as an excuse. Learn how to beat the markets and the brokers.
