brian was able to get a working example of this on 9.72 and with slight modification it can probably run in 9.73. The question was simple: look at current price and compare to previous day session high and low. If price is above it prints out buy, and if below low of historical previous session it would print out sell. At first I struggled due to my weak knowledge of Java, but brian displayed in his answer selected as best, how to use the current and historical prices for comparison. Very rudimentary, but important.
This is the current code that is supposed to take current price and compare it to prior session and if above high give a buy print out and if below low give a sell print out. In the 9.72 API this code did nothing because it did not properly connect data types.

This code currently has out put like the following:

-1.0
-1.0
Notice the high and low daily are showed for two sessions, that is truly amazing. But when trying to use those high and lows in tickprice it is not being remembered and returns -1.
I removed a bunch of stuff from your code and added the parts needed. After connecting wait for nextValidId to start requesting stuff. Get the history and set highs and lows. Get mktData and check the last price, buy/sell as needed.
