Spring Information Broker Review

I found out several weeks ago that the chart Gold vs USD shows significant deviations compared to the market especially in the timerange 2:30pm to 4:30pm local time Germany. That's the timespan when my girl advised me for trading transactions. When telling my concerns to the broker the only reply was "it`s normal, each platform behaves a little different". All followes international standards. I call myself an idiot, all together I burned around $60.000 in half a year. What a shame.
