Now I think market is more unpredictable than weather. There r only a few movements in weather system that r a mystery but in forex all loosing trades of a pro means mystery moves by market.

Yes, with the weather, at least when its raining you can tell its going to rain for a while.  Forex not so much.

I think the market will not behave like the weather. when certain conditions, market movement will be very aggressive. growth factors are very influential in the trade.

Its definitely difficult to tell when the market is about to be very aggressive - except in retrospect.  I wonder how many years of backtesting weather forecasters use for their data?

very true friend. very difficult to foresee and predict the price movement of market trading. required extensive knowledge and great skill in trading. and estimates may also experience errors.

Yeah forex market sometime behave like weather and some time there are higher fluctuation and sometime there are low fluctuation so we have to see the market first before we place any order.

Yeab absolutely and we should have to trade in market according to market news only and have to follow them and then only place the order.

Although no one can predict with 100% accuracy where the Forex market will be at a future point, i think with computers, you can input enough historical data, enough influencing factors, enough news-reading-analysis, enough pattern recognition information for these mega-computers to process a billion zillion calculations per second and make predictions that whlist not perfect, are strong enough to go on and make LOADS of money.

Someone, some team, somewhere in the World is almost definitely already doing it! Of course it takes investment and money to achieve this but someone has already done this im sure.

Final thought: even then the computer can't predict a market crash brought on by a natural disaster or terrorist event so if the investors are greedy and not careful they can still get burned but perhaps the computer is smart enough to close losing trades early and "wait" to assess the evolving situation based on live-news data.
