"svm prediction module guidence"

Hi,
I am doing an academic project on stock prediction. while trying to figure out how SVM works, i bumped into rapid miner. I am using it since last 2 hours and i am not able to figure out how to predict values for future dates (horizon > 1). I increased the horizon size but then it shows me 1 future value for every value in input data (if horizon is 5, it shows me 1 value for every input which is suposed to be a predicted value on 5th day after current input). Is there any way by which i can display future values in proper sequence e.g. day 1 - predicted value 1, day 2 - predicted value 2, etc.
also, is there any way by which I can improve the prediction accuracy ?????
also, can i somehow incorporate such a particular prediction module in my java code for my GUI or should i call rapid miner explicitly from my java program ??? (i just want to use the SVm prediction module and not all the features of rapid miner)
It would be great if you can help me out
I am attaching here the XML of my test file
