Forex News and Currency Strength - Is it really as simple as that?

'Playing' around with small 0.01 orders at the moment, and this seems to be working so far.

Relying only on the following:

NZD/CAD

1. Currency strength, on OANDA, confirms NZD as losing strength against the CAD over both the week and month.
2. Positive GDP results from Canada indicating that economy is performing well.

So, waited for a 15 minute candle to close after the news (to confirm direction), and placed a sell on NZD/CAD. B/E set when it reaches 20 pips profit. TP set at the next visual support level. Order is a 1:3 RR.

I've used no indicators at all.

Is it possible that it can really be this simple? Looking for a currency to perform better than the market predicted, and then placing the appropriate order against a weaker currency?

It does make me think trading purely on sentimentals may be better than technical?

Just interested to see if others have made profits doing this?
