If the price is actually not going anywhere, then the lines that you draw through the highest highs and the lowest lows will either be horizontal and parallel to each other, or they will be converging (drawing closer together) or diverging (drawing apart). If they are horizontal, you might use them as support and resistance lines in the same way. So if the price breaks above the upper line you would buy, expecting it to resume in that way for a bit. Equally, if the price breaks above the lower line, you would sell. Like all foreign exchange strategies, these aren’t warranted. There is always a risk of trades going against you, so you check your signals against other indicators and always use stop losses. Always test your system in a demo account before going live. These steps will help you to develop a successful currency trading strategy. It is well known in the currency trading world that the trend is your friend and any currency trading strategy based around following a trend is probably going to be both straightforward and effective. It is really easy to make trend lines on any currency exchange chart, but most folks prefer to use candlestick charts for this because the candlesticks are such a clear visual signal. When trend lines are forming, you can use them as a signal to buy or sell the currency pair.
We need not look for further examples than Keltner Bells. The first step in using trend lines for a foreign exchange trading technique is to establish whether the market is rising, falling or is stable within certain parameters. If the price is rising
If the price is going up, first draw a straight line through the highest highs on the chart. This line will be sloping upward. Then draw another line thru the lowest lows on the chart. If this line is also going upward and is roughly parallel to the 1st, you’ve got an rising trend. You can then use these two lines as support and resistance lines. any time the price hits the top line you could sell, on the presumption that it will fall back.
or, any time the price hits the base line you might buy, on the assumption that it will shortly rise again. In this situation you follow the trend which is often a better methodology. 2. If the price is falling
If the price is going down, you can follow a similar strategy to the previous system. The lines you draw will be going downward but you would still buy when the price hits the lower line and sell when it hits the upper line.
