In order to profit you need to understand how the Forex market is structured and how Smart Money makes their profits so you can intelligently participate in the order flow. If you trade solely upon "visual chart analysis" such as moving average crossovers, head and shoulder patterns, and pin bars without any other analysis you will be frustrated. Smart Money moves price in a very deliberate way and if you become familiar with their repeating patterns of movement it will help your trading immensely. It is your job as a trader to find a repeatable way to enter the market and exit with a reasonable profit without suffering a large draw down.
In order to profit you need to carefully analyze the market and selectively enter only when conditions are favorable. You must use high probability setups with a well developed trading system that is market tested. It is not important what trading system you use-it is important how experienced you are with it and how well developed it is. You must always exercise patience.
Of the 3 major sessions Asia has the smallest trading range. Asia is a reset for the market makers and dealers who are gearing up for the trading day in London and New York. The real action starts during the London open. The high or low of the day is usually set during London with follow through into New York. There is a flurry of activity at the London open followed by ranging movement and there is usually increased activity again in the "Valley" 5:00-8:00 am EST USA prior to the New York open. If you start to pay attention to this time slot you can find some good trades at this time.
If you are trading range bound rotations on short time frames you should only trade when the market is volatile and Smart Money is active. Smart Money moves price to their targets more directly and in a shorter time period at these times. If you trade during periods of low volatility you need to allow for the passage of time for your trades to become profitable and also allow for a reasonable draw down in your position. It is unrealistic to expect that price is going to race to your target the moment you open a position in low volatility conditions. The only time that price is going to race to your target is if you trade important news events. Trading important news events does carry increased risk but you can learn to trade the news profitably. You can learn to position yourself on the right side of the order flow and handle the fast price movement. This comes through experience and conditioning.
