Trades on the Bancor Network are represented by a single-hop in all cases. TokensTraded event tracks the key information. The sourceAmount is provided by the trader in exchange for the targetAmount (which already has the targetTokenFee subtracted from it).
Behind the scenes, the bntAmount is the BNT volume that facilitates the trade and has the bntFee subtracted from it.
