Building Trading Strategy in Java API for Interactive brokers

I want to use the code for various symbols. I day trade weekly options. So basically each night I have to change the code(only change symbol and option contract) to instruct java api what to trade tomorrow. Trade Conditions: 1. The opening price of the underlying stock is within -.5% to .5% from the previous days closing price and the option price(strike of my choosing) is no more than 25% greater from the previous day's closing price. If the condition is correct, then start a position buy 1 option contract with a REL order and a limit of 3.5. 2. If the underlying stock is down more than .8% from the time the option got filled, then sell the option position with a rel order and a limit of 1.00. 3. If the stock goes up more than .5% from the time when the order filled, then move up the REL order so that I can get out of the option position at break-even. That is if the stock goes back down(after going up .5% or more) to the price(the price of the underlying stock when the option contract got filled), the use a REL order to get out. 4. If the stock is up 3% or more from the time when the option got filled, then use snap to midpoint order to get out of the position and capture profit. I am open to suggestion. Kindly let me know if the project needs more clarification.
