Example 1: Standard lot trade with $7 commission
You trade 1 lot EUR/USD on an ECN account. Broker charges $7 round turn. That's your commission—period. Add maybe 0.2 pip spread ($2) and total cost is $9.
Example 2: Scaling into a position
You enter with 1 lot, add 0.5 lots, add another 0.5 lots. That's 2 lots total. Each entry and exit gets charged. With $7/lot round turn: 3 entries + 1 exit (partial closes complicate this) = $14-$21 depending on how you close.
Example 3: Comparing account types
Broker A: Zero commission, 1.5 pip spread on EUR/USD = $15 cost per lot.
Broker B: $6 commission round turn, 0.3 pip spread = $6 + $3 = $9 cost per lot.
Broker B saves you $6 per lot. Trade 100 lots/month, that's $600 saved.
