Sorry for the late replay.
I trade bts for eos on the bitshares DEX (decentilized exchange)
For example i bought 120 eos for the price of 40bts per unit.And then i wait for 10-20 days for example and i sell in ladders for 50bts,60bts and 70bts if possible :)
That is a BIG IF the price of eos goes up and the price of bts goes down or goes sideways.
If its the other way around you just hold your eos and wait for the price to be higher than you bought.
Hope this helps
