Forex Trading with Fibonacci
Trading on the foreign exchange markets is a complex
business to say the least, and so it will come as no
surprise that almost every trader will spend a high
percentage of their time searching for anything that will
provide an extra edge.
Fibonacci - or to give him his full and correct name
Leonardo Pisano, was an Italian mathematician who lived in
Pisa in the middle ages.
Amongst his many claims to fame he is credited with
calculating "The Golden Ratio" and "The Fibonacci Series"
by which the next number of the series is obtained by
adding the last two numbers together...... 0, 1, 1, 2, 3,
5, 8, 13, 21, 34, 55, 89, 144, 233, 377, 610, 987, ...
The thing that is quite surprising about the Fibonacci
series is that this mathematical sequence naturally occurs
so very often in nature, and in so many facets of life.
This may have something to do with why it is felt that
Fibonacci has a part to play in helping us to trade on the
Now stay with me here, because we need to take a look at
the all important inverse ratio, because it is the use of
the inverse ratio that we traders are most interested in.
If you divide one of the "Series" of numbers by the
previous number in the series you will always get the
answer 1.618 and if you divide a "Series" number by a
"Series" number two along you will always get the answer
2.618 or put another way the inverse ratios of 0.618 and
Do you really need to know any of this? Well yes and no.
Sometimes it puts things into perspective of you understand
how they came to be used and it is of course extremely
important to understand as much as possible of what is
going on in the minds of the other market participants.
You will, if you have been trading for more than a short
while, have come across the retracement levels of 38% and
62%. Guess where they were calculated from.
Yes, they are the rounded numbers derived from the
Fibonacci series and portrayed as a percentage.
Many traders freely state that when a retracement is
underway, price will generally "turn" at one of these
levels and if it does not, then it is no longer a
retracement, it is a reversal.
Over time an extra level has been included which is 50% but
as far as I can ascertain this is not a number that is
attributed to our friend Leonardo.
So what is the truth of all of this?
It is true that Leonardo Pisano, was an Italian
mathematician who lived in Pisa in the middle ages, and it
is likely true that he was the first to document "The
Golden Ratio" and "The Fibonacci Series".
As to whether the Fibonacci levels will work when used as a
trading aid is, I believe, largely dependent upon how
popular the Fibonacci trading levels theory is at any given
If the price of a currency pair has reached 1.5670 from a
low of 1.5282 and then price starts to retrace, and if the
vast majority of traders who are active on this currency
pair believe that the Fibonacci levels are a valuable
trading aid, then price will most likely bounce at the 38%
level of 1.5525 or at the 50% level or at the 62% level.
If on the other hand the majority of traders who are active
on this currency pair believe that the Fibonacci levels
have no trading aid value at all, then price will most
likely settle at whatever is the current perceived market
value of that pair.
Do I use Fibonacci levels?
Well to tell the truth, I do watch the levels, but only
because so many traders believe that they work, and maybe
this belief alone is enough to endorse their use.
