Verdicts & Settlements

Trader Sued for Abandoning Partnership and Taking Black Box Futures Trading Software — A futures trader developed a black box electronic trading software program, and formed a partnership with other traders to obtain clients to trade S&P 500 futures using the software. However, the trader withdrew from the partnership and took the trading software with him, and the partnership’s clients closed their accounts. The partners sued the trader seeking lost profits from the commissions that the partnership would have continued to make from its clients’ trades. We successfully defended the trader on the basis that the partners were planning to steal the software and kick the trader out of the partnership, and the partners had further violated their fiduciary duty to the trader by misappropriating partnership profits to their benefit. The trader was allowed to leave the partnership with his trading software, and the lawsuit was dismissed.
