When the result out, the price should break out in one direction, instead of swing largely at that time point, that's my opinion. Currently the gbp.usd is 1.637, let's say, the price just before the result comes out is 1.63, so how about set 2 mkt stp orders on the upside and downside of 1.63? Or just set a market order after see the result, will it be too slow?
