Currency traders wary of a weekend diplomatic resolution to the gulf crisis left the dollar mixed Friday in New York trading despite a Soviet crackdown in Lithuania that weakened the German mark.

Instead of investing in dollars, players worked technical positions in which they simultaneously sold German marks and bought Japanese yen, or moved funds into the currency of neutral Switzerland.Dollars, sought most of the week as a financial haven when gulf tensions rose to a high pitch, were seen as risky because a peace effort by U.N. Secretary General Javier Perez de Cuellar might eliminate their war premium.
