We will be looking at different elements of Ichmoku system with reference to GBP/USD as of Friday 9th October 2009.
We have already defined Tenkan Sen (TS), Kijun Sen (KS), Senkou Span A, Senkou Span B, the ichi kumo or cloud and Chikou Span (CS). To avoid confusion I will use the abbreviations in the brackets when I refer to these lines.
OK we mentioned that TS and KS act as a pair of simple moving averages (SMA). The only difference being that these two Ichi line are based on the moving average of the highest high and lowest low over a specified period.
The normal period used for TS is 9 period. For KS is 26 periods. CS is the current price plotted 26 period behind. SSA is the average of the TS and KS, plotted 26 period ahead. SSB The average of the highest high and lowest low over the last 52 days, plotted 26 periods ahead. The area between SSA and SSB is called kumo or cloud.
These periods 9, 26, 52 and 26 are based on the original periods used in Ichi in Japan. Japanese being hard working people as they are used to work 26 days in a Month. 9 days was 1.5 weeks (yes 6 working days in a week) and 52 was 26 x2 = 2 months. Thse periods are still widely used and IMO you can use them effectively in 1 hour or 15 minutes charts. They are opinion holders that believe that ichi is more suitable to longer periods. I believe one of the empirical factors that every trader needs to consider is the appropriate time-frame to use for every indicator and like any other indicator such as SMA different time frames should be considered.
In the attached diagram we have:
Currency:GBP/USD
Time frame: 1 hour
Indicators: All Ichimoku components, TS in purple, KS in blue, CS in orange, SSA in black, SSB in grey and bullish cloud with red shadow and bearish cloud with yellow shadow.
The current price is shown at 1.5844 with a green arrow. TS the faster line is below the slower line KS that in normal conditions implies bearish conditions. Note that TK crossed KS from above in the section marked as 26 periods and shown with a blue ellipse. Also note that the candle is below this cross giving more prominence to the bearish signal. We will come to these a bit later.
CS the orange line is the closing prices shifted 26 periods behind. So what is the point of this? First it is used as an indication of bearish or bullish signal. Secondly the fact that you draw prices as a line (as opposed to candle) visually makes it easier to see the support and resistance at various points (the bends). Personally I find drawing trend lines against CS much easier with a better clarity. I have already done so from 1.5996 to 1.5835 (the trend line in 52 periods section), for that sharp fall.
Now let us go back to SSA and SSB. SSA (26 period) is the faster of these two lines and as such reacts to price changes faster than SSB (52 periods). So what is the point of shifting these two lines 26 periods forward from the current price and filling them in between! Let us assume that the price will always respect equilibrium. After all every single indicator that we use (SMA, Bollinger bands, MACD etc) all rely on the averages of prices in one form of the other. The equilibrium or mean is the preferred position for all things in life. Imagine boiling water. By putting heat/energy you are exciting molecules and forcing them to move away from each other. As soon as the water cools down, the molecules get closer together and back to where they were i.e. equilibrium. Anyway you get the drift.
Let us go back to the definition of SSB. It is the average of the highest of the high and lowest of the low in the previous 52 periods shifted forward 26 period from the current price. In the section on 52 periods you see the highest of the high (the green candle). You just about see that blue circle at 1.6119. Also the lowest of the low in the past 52 periods is shown by the blue circle just before the current price closing at 1.5825. So the value of SSB is (1.6119 + 1.5825)/2 = 1.5972 (see the graph). Similarly if you work out SSA it turns up to be 1.5932.
Note that for most of the projected period SSB remains flat. Why is that? Because for the majority of this period the highest of the high and lowest of the low were not moved. In contrast SSA has been moving faster as the price moved higher and moved down as the price started moving down crossing SSB at the green ellipse as you can see on the graph in the section “26 periods forward projected”. That crossover is a bearish signal that coincides with the start of the downtrend (that big fall as shown by the trend line). We will come to it later
Now the cloud is the area between SSA and SSB. There is the current cloud (or the cloud I call it) where the current price is and the leading cloud (the one projected 26 periods from the current price). The leading cloud is primarily used to indicate probable future support and resistance levels. Top of the cloud indicates the first level of support and the bottom the second level when the price is above the cloud. Conversely, the bottom of the cloud indicates the first level of resistance and the top the second level when the price is below the cloud. A price above the current cloud indicates a bullish trend and a price below indicates a bearish one, while price within the cloud indicates a potentially trendless or range bound situation. The thickness of the cloud shows the level of historical volatility, as well as the strength of support or resistance. The ticker the cloud the more volatile is the price. Volatility simply means rapid movement of the price within a short period. If the price is trapped in the cloud then the top and bottom lines are resistance and support respectively.
