I know very little theory on NN's. I do know why they use tanh. This is because if one indicator goes long or short with very high or low levels, it could unbalance a net and bias it in the direction of the one input. To prevent that the peaks are rounded off by the tanh function. This way every input gets only one vote.

Best Wishes,

Bob
