narxnet early prediction problem

I have developed a NarxNet to predict the next High on a stock market asset. When i use the early prediction the network only can predict the y(t) once i have provided two delays with its targets and a new value with a target too. The problem is that at the time of using it in real time i can't have the last target, i mean the value to be predicted target so i get the last one y(t-1) and a NaN for the next.

How can i use then the early prediction to get a prediction of the next value?

Thank you for your help

Dear Victor,

You can use close loop to predict next values in narxnet, for example:

% one-step-ahead prediction

perf = perform(net,Ts,Y);

[Xs1,Xio,Aio] = preparets(net,inputSeries(1:end-delay),{},targetSeries(1:end-delay));

[Y1,Xfo,Afo] = net(Xs1,Xio,Aio);

[netc,Xic,Aic] = closeloop(net,Xfo,Afo);

[yPred,Xfc,Afc] = netc(inputSeriesVal,Xic,Aic);

multiStepPerformance = perform(net,yPred,targetSeriesVal);

view(netc)

also this information aren't efficient
