not far away from the truth but i would not agree totaly.
see i was long time in gambling bussines,both sides of the tables and i am in forex around 3 years and i can say if you are smart enaugh,patient,disciplined you can have some advantage in forex market.of course you can have some advantage in gambling also (bad roullete table...or something else) but it is not the same.
other way if you are stupid ,inpatient,undisciplined,uninformed (it sound like me ) then it is gambling,big gambling.

One thing what i do not understund is how they make quotes for forex,does every big bank quote bid/ask,or it is perhaps centralised (i know they say it is not centralised) ,something smell there...they are cheating to us but not always i think,news time is where we could do domething for sure but as you know in news time most brokers make big spread or even froze quotes...

few words about your system,we can trade forex in thousend ways and you can say it is random game,but think ,if lot of BIG traders are using some moving averages or pivots or fibonacci levels (and they do) then it have some influnce on the market and then it is not so random...it have some logic
