DBN+NN for predicting the trading direction in finance

[stutys]

I use DBN+NN for predicting the trading direction in finance, but the probability of rise or down alwarys stay the same? only when i change the test data, the probability may change. For example, if size(test_x) = [100,2], then the output matrix has two constant columns, such as [0.46 0.54; 0.46 0.54; 0.46 0.54; 0.46 0.54; ...]
thanks for your answer!
