The market is so thin at the moment I wouldn’t suggest to trade only 1Instrument such as Euribor, even if you trade outright, boxes, fly’s, double boxes or condors.
The only way to hedge the risk is to try use the above strategies in other instruments as well such as Eurostocks, Eurodollor, Sterling ,etc.
If you are just trading Euribor boxes only, just 1 instrument, if I was u I will be doing outright with S/L and T/P, because even if you see market cycles for the product using CQG or whatever there is no range whatsoever. This depends also in your margins 🙂 if you can afford them.
Finaly in terms of risk:
Box : -1 +3 -3 +1 or 1 -3 +3 1 =Not very volatile (may find ranges)
Double box: -1 +2 0 -2 +1 = Volatile (ranges maybe broken)
