My Currency Trader Magazine June Article Check it Out ! ~ forex trading jobs in london

0

As many of you may already know - if you have been following my blog for a while - I have become a somewhat "regular" contributor to Currency Trader Magazine, one of the most well-known and respected magazines published in the area of forex trading. Besides featuring very famous and well-respected authors such as Barbara Rockefeller, the magazine tries to give people quality articles about both fundamental and technical aspects of currency trading. I have to say that Currency Trader Magazine had become a monthly "must-read" for me before I started writing in it, with its articles being very good to catch both a birds eye view and a practical perspective over current market conditions but being an author now gives me the opportunity to humbly contribute to this great monthly magazine. On todays post I want to talk to you a little bit about my June article and how I think it provides very valuable information about market inefficiencies and the way in which they evolve over time. You can download the June edition of the Magazine -containing my article- for free here(if it is already August and youre reading this then you will have to purchase the issue separately).

The article I wrote for the June issue attempts to address a significant question I had been asking myself for a while. Is the market so inefficient that the movements within trading sessions are predictable ? I wanted to take a look at the Asian session in particular and answer this interesting question regarding whether or not we could look at this session for a period of 4 years and predict the future magnitude of absolute movement and the range within this trading session. Would it be possible that the market moves in a predictable way during this period of low volatility ? I started to do some research to find out.

In the article I go through an analysis of the Assian sessions range and absolute movement within the past 4 years on the EUR/USD, EUR/GBP and EUR/CHF attempting to find a "pattern" of evolution that could signal the existence or absence of a "predictable movement" within this session. Of course, part of this research was inspired in the fact that many commercial system sellers have attempted to exploit inefficiencies around this session that have worked for a while and have then become obsolete. I have always thought that there is some predictability around the Asian session but attempting to exploit it without any adaptability is simply a behavior prone to eventually fail (you really wonder how many of those sellers are really traders).

The results I found were - for me - absolutely breath taking. The analysis of absolute movement values for the three different pairs revealed nothing spectacular, showing that the ranges evolve widely as the market changed. Effectively this proves why Asian session scalpers are doomed to fail, the character of the session changes tremendously with time and exploiting it using such systems in the long term is not going to work. However I then took a different look at the picture and evaluated the range and absolute movements differently - taking certain additional market elements into account- obtaining a wonderful result. As a matter of fact, what I found confirms what I have suspected for a long time.

Not only are the Asian session conditions predictable, but they are almost the SAME for the EUR/USD, EUR/GBP and EUR/CHF. This means that my article found a key part of fundamental market behavior, a characteristic of the market that appears to remain unchanged as time goes by. Of course, the details of this analysis cannot be revealed here (you need to go ahead and read the article ! :o) ) but you will see that my analysis shows clearly that the Asian session is technically inefficient and that creating systems to exploit this inefficiency is indeed possible. During the next few months I will be working on the creation of several different mechanical trading systems to use this research to show that effectively the behavior within the Asian session lends itself to mechanical exploitation.

Alternative Adaptive Criteria Introducing a New Feature of Teyacanani ~ forex trading jobs in uae

0

One of the main problems Teyacanani has faced from the moment of its release is the use of a daily ATR indicator with small period values (3 to 6) which are extremely sensitive to the presence or absence of Sunday candles within the brokers feed. The fact that these periods are small makes the presence of these candles extremely influential, something that doesnt happen with the turtle system or Watukushay No.2 which use much longer ATR period lengths (14-20). In order to solve this problem we have implemented an EA that generates an offline chart without Sunday candles but this system does not work on some brokers for reasons pertinent to each brokers particular software implementation. On todays post I want to introduce a new solution to this Teyacanani problem showing you a new type of adaptation that uses the ATR indicator but does not rely on daily indicator data, effectively eliminating the problem of Sunday candles for this EA on brokers where our non-Sunday solution does not work.

What is exactly the problem with Sunday candles ? When you calculate the value of a daily ATR indicator, the code calculates the value of the ATR assigning the same weight to the values of all daily candles. On brokers where Sunday candles exist these candles are treated - within the calculation of the ATR - as if they were regular daily candles when they usually have only 10-20% of the regular volume of a complete weekday. When you calculate the value of the daily ATR for a small number of periods you will often get a very significantly smaller value for the indicator when compared with an indicator where no Sunday candles are involved.

Many people - me included - will think here that the best and easiest solution would be simply to decrease the values of the filters on the EA to compensate for a "lower overall" ATR value. However the main issue here is that no accurate 10 year backtesting data with Sunday candles is available to test the strategy and this therefore makes any modification done impossible to evaluate with metatrader 4. Possibly diminishing the value of all filters might work, but there is also a very important possibility that this will simply not work as - when low ATR periods are used - you might get days where the ATR is calculated without the Sunday candle. For example, a 4 period daily ATR on Friday only counts Friday, Thursday, Wednesday and Tuesday, leaving outside Monday and Sunday. Introducing a modification that decreases all overall ATR related variables will probably have an adverse effect on these days.

What is the solution then ? The easiest thing to do here was to find a way of removing the Sunday candles from the chart, merging Monday and Sunday candles to get a "clean feed" that simulates that of a broker without Sunday candles. Using an EA called "without Sunday", available from the mql4 code database, we were able to eliminate the problem for most brokers. However, due to limiations inherent to some other brokers - particularly Forex.com - this solution wasnt able to work correctly in some cases.

My solution for this case was to find another adaptive criteria that could avoid the usage of the daily ATR indicator. I thought that if you could simply take a lower time frame and "extrapolate" you could maybe obtain the same results as you would with the regular daily-ATR solution. So my implementation was therefore really simple. Take a given hourly-ATR period indicator and then multiply it by X so that you reach a magnitude similar to that of the daily ATR indicator. You would still get evolving adaptability as market conditions change but of course, the speed and character of the adaptation would change.

In the end I found the results showed above for the EUR/USD and GBP/USD currency pairs using Teyacanani (Jan-2000, Jan-2010). The trading results - after following the same optimization procedure as with the original Teyacanani version - were very similar to those obtained with the daily-ATR solution, showing that a given hourly-ATR could in fact extrapolate to a daily-ATR without great changes in the effectiveness of the adaptation against volatility. However it is clearly notable here that this approach does not tend to work for all currency pairs. Some instruments like the NZD/USD and AUD/USD tend to have larger and more changing hourly volatilities that do not provide an adequate reflection when extrapolated towards daily volatility. The results obtained for these currency pairs are therefore poorer than when using the regular Teyacanani EA.

In the end, what this exercise has taught me - and I hope I have transmitted to you within this article - is that volatility adaptation can be carried out successfuly through many levels and that alternatives to daily-ATR based adaptation are clearly possible but may prove to be different for instruments with different characteristics. Right now this new version of Teyancanani - now available within Asirikuy - provides users of brokers that could not implement the WithoutSunday solution with a version of Teyacanani that can run on the EUR/USD and GBP/USD with similar profit and draw down targets. Volatility adaptation has always been one of my great areas of interest in automated trading and hopefully within the next few months and years I will be able to develop some robust and creative adaptive criteria :o).
