## Cost is more than spread
Many platforms advertise zero or very low spreads, but Raw accounts may charge commission and overnight positions may incur swap.
## Simple calculation
For short-term trading, check spread plus commission plus slippage. For overnight trading, add long or short swap. Frequent funding users should also check payment fees.
## When comparing brokers
Compare the same instrument, account currency and trading session. Spreads can widen around news and low liquidity, so do not rely only on minimum website spreads.
## FXCN advice
Keep real records for each platform: open price, close price, commission, swap, slippage and withdrawal fee.
