The ea needs a trending market. Otherwise it won't open any positions. that's good we don't want to get caught in a sideways market. I like that saying, "Better to be wishing you'd gotten in, rather than wishing hadn't gotten in".
so even though the pairs are dipping in and out of the hi lo channels it's all still sideways. The multi time frame moving averages will identify when there is actually a trend worth risking a trade. So maybe nothing for a few days. We can wait. And be ready for when it's right. We have lots to do to get ready.

Hi Jiva,...
so how to deal with this.
JM211o has very kindly brought this to the forefront while I am having a great old time optimizing perfect "curve fitting" settings. Something Taiyakixz has been hounding me about for months.
You are mostly "curve fitting" he chides.
Anyway, we all will agree there must be some "curve fitting", so I'm getting really good at!!!
But how do we deal with the inevitable, change in market conditions?
JM offers that backtesting and curve fittng for at least 3 years will offer some protection. The graph won't be so pretty, there will be dips but overall an account balance will be protected and most likely show some profit if the ea has any statistical edge to it at all.
At first glance this looked like the solution. But then my "evil" mind taunted, "There is no guarantee that simply going out 3 years would offer protection from changing market conditions. Maybe the market would change after 3 years and the optimized setting for 3 year period would become ineffective". In other words a curve fit for 1 year or a curve fit for 3 years or even 5 years would all have the same inherent short coming of becoming ineffective at some point. The problem is not knowing when that point of ineffectiveness occurs until the losses start!!!
So 1 year, 3 years, 5 years, 10 years!! All the same problem.
What to do?
What I am thinking, and I share it with the forum, is that market conditions most likely do not change overnight (of course we get those wild spike and dips but I mean serious change over an extended period of time), they begin to change gradually as the participants adjust to the new economic environments. So by performing optimizations regularly, on a daily basis would be superb... then whatever changes are occurring should be gradually incorporated into the optimized curve settings.
Not go out a million years, but zoom in on a day to day basis if possible, if not daily, then surely a weekly optimization should account for any changes in market conditions as they happen staving off losses.
If that were the procedure it might be possible to optimized for 6 months instead of 12 months and get an even higher profit curve. But 12 months seems reasonable.
6 months might be introducing a bit more of a risk factor than we might want. With higher profits comes higher risk. It's already risky enough!!!
But we can research it a bit at some point.
Any thoughts on this. It's really central to using an ea.
This is a very central point about expert advisers. When the market conditions change they can lose their "wisdom" and eat an entire account balance in about 3 gulps.
so how to deal with this.

But how do we...
What I suggest is as RR has shown in his "Old Dog new tricks" Thread? Traders agree (1) optimization is necessary to give best performance results, and (2) markets for each pair change over time, thus outgrowing the EA's. If an EA can be coded it would seem logical an internal module to any EA could contain capabilities to self optimize using various dynamic measurements. One approach short of neural network applications would be to adjust the architecture of EA to variable mtf look back tables (PA) from which calculations could maintain in-turn variable set files. This could be done weekly, or bi-weekly or monthly using a standard 5 trade day week. Updates could be run after market hours (weekends) or every fourth week, etc.
We have been fighting a losing battle (in most EA's) with static programming
following lagging indicators.....! If we moved from static setting parameters needing manual optimization to flexible set adjusting methods the EA's built on
approaches moving in concert with market price movements may be a worthwhile direction involving toward "real hands-off" or longer term non-intervention?
Just thoughts....

Hello Jiva34 and everybody at the Thread this is my first post, I am a Newbie in Forex, I have been trading for less more than 6 months, and have been reading Forexfactory's Threads since 3+ months
I am very interested in your system and have started testing EA in EUR/USD H1 since yesterday, Demo account with Instaforex, Good results since then, I also tryed to backtest EA with "EurUsd" but no success maybe is because I run MT4 plataform inside Linux, anyway Thanks for your priceless Effort and your good will with all of us
.
If there is a Way I can contribute this System and Thread I will , Please be so kind of pointing what I can be usefull to help. (I am graphic designer, Web and Linux programmer) maybe a "logo" for this incredible EA could help people here and elsewhere to trigger mentally here, just an idea)
