/**
* Trade-Lookup transaction <br/>
* TPC-E section 3.3.3
*
* H-Store exceptions:
*   1) There are a lot of output parameters for some frames. Although, since they are not required for the transaction's
*      output, we do not retrieve them from tables, but the statements are executed anyway
*   2) getTrade_frame2, getTrade_frame3 SQL: LIMIT is set to 20 (the default value for the EGen), however it must be 'max_trade' parameter.
*      H-Store does not support variable limits
*   3) getHoldingHistory is modified to use a self-join instead of an "IN". H-Store does not support "IN"
*   4) getTrade_frame2 and _frame3 are given "CMPT" string as parameter, since we cannot specify it in the SQL query string -- parser error
