Can forecast indicators - need an idea for trading

Hello, fellow traders
I've got the following case.
Recently I'm working with ANN in order to use them in Forex trading. Currently I've received some intermediate results - I can predict the movement of indicators with 75%+ accuracy (on some indicators up to 90%) - for example, my ANNs can forecast the moves in sma or rsi one-two days ahead pretty accurately.
But here I've stuck with the following problem: how this knowledge can be transformed into any useful strategy? The question is: whether its possible to transform future values of indicators (which can be predicted quite accurately) in some reliable trading signals?

if you can forecast the RSI for two days why you are not able to forecast the price. I thought the RSI goes with the price???

Yes, in fact you're right - RSI (as well as all other indicators) is just a function of price. And I've actually tried this. But he is the thing. Forecasting the value of RSI (or moving averages) hold some level of error itself - so it can be totally wrong (shows negative change while in reality it will be positive) as well as error in value itself (forcast shows change in 0.5% while the real change appear to be 0.1%). This doesn't look much BUT when I've tried to deduct the next price based on indicator value (for example for SMA(5) we need just solve a simple equation with one unknown) I've received really massive errors - in general the predictive power dropped almost to 50/50.

BTW I've just got an idea - we can try to deduct the price value based not on on on several indicators - for example, take average of the deducted values.
