How to build a very profitable EXPERT ADVISOR

Hi All,

What are the fundamentals of building a very profitable expert advisor?Almost all entry-exit ideas based upon slope change or some kind of indicator crosses.

I am NOT INTERESTED in anybody's expert advisor or set of indicators.I just need some advice from experienced system developers, coders.


----MY REAL QUESTION IS ,My entry-exits fit the certain forex pairs in certain time frame VERY WELL.The thing is how should I quantify the certain forex pairs in certain time frame ? What to use ?Relative-strength?Profit factor,sharpe ratio?
So the expert advisor can switch in between the certain forex pairs in certain time frames.


---Do you reduce the frequency of signals in your expert advisor?If yes HOW? Do '' take profits'' or '' trailling stops'' give extra edge in your expert advisors?

---Do you set your ENTRY-EXIT algorithm as :BUY SIGNAL - SELL SIGNAL ( REVERSE BUY SIGNAL THEN ENTRY SELL) - BUY SIGNAL (REVERSE SELL SIGNAL THEN ENTRY BUY) in your expert advisor ?

---Do you use market state analysis in your expert to reduce the frequency of signals ?
Market state analysis means for example you use moving average crosses to identify strong trend-weak trend etc..I have found this approach quite difficult to detect the trend and attempt to exploit it.Or maybe I am stupid and somebody has already succesfully exploited the trend with market state dashboards and applied it to their expert advisor?What is your opinion?

---Do you use only the fast indicators for your entry exits?If yes ,how do you avoid or reduce the frequency of signals?Sometimes M15 time frame give less and more profitable signal then the M30 time frame. How to quantify this? What look for ?

---Do you use fast indicators (for razor sharp entries) and slow(lagged) indicator combinations in your expert advisor?If yes how do you combine the fast and lagged indicators?How do you seperate the buy-sell-hold reasonning in the expert advisor? Do you use some intelligent reasonning(I dont meant only neural networks by intelligent reasonning)?

---Do relative-strength analysis give any improvement to an expert advisor?

----What is momentum(not momentum indicator) trading ?

Money managment-risk managments are secondary, they dont improve the entry and exits, this is my opinion.

Thanks.

Usually people post their trading system and then ask if they should do this or that to improve things.

Your questions are like asking a thousand people how in their particular methods in their systems they implement solutions.

I understand that you probably don't want to discuss the particulars of your method but I doubt you are going to get solutions to your problems being so vague. The answer to all your questions are: Yes. No. Maybe. It depends.

Hi

If you read my post again I never asked anyone how in their particular methods they implement solutions.
I believe my questions are clear and specific.

I think a good system need to be market adaptive. For example I use a flexible stop loss calculation. for example.
minimum stop loss 10 pip. //stop will never 1-2 pip
if atr*atrmultiplier is greater use it //if market move is big use greater stoploss
if spread*spreadmultiplier is greater use this. //use bigger stop by news
if strongest support is higher use this. //watch for S/R
