i have six pairs up on screen. usd/yen, euro/usd, stg/yen, euro/stg, eur/jpy and cable. i wait for ca2's. i dont take them all. partly depends on other stuff i have on or a view on the currency. for example i missed most of the text trades that were shorts a week or so ago just because i liked stg and was long cable. i am not nearly as active as i should or would like to be due to time pressures. i have a small pub business (previously i was a bond trader in the 83 to 96 period). longer term i am downsizing my business as after 12 years i want more time off and less staff and then i can trade more full time.
as for advantages, it depends. i find it helps me as you are more aware of whats going on in the bigger picture. we have had several trades on the service that looked ok and then were undermined by other things. the stg/yen pair is not one i would have naturally gravitated too as spread is so wide but its kevins fav and his performance chart was fantastic last year so i got involved. the volatilty has kept it excinting but the cable trades have offset the losses i made on the service. i guess i could have got them both wrong but i didnt so it was ok.
to be honest i just think i would find it boring to look at one pair. by the way that trade got stopped out on ca4 for 120 pips profit. the thing about fx53 is that it doesnt do all the work for you but it really helps if you are time short and kevin showed last year that it can make great money
