Forex cashback (also called a rebate) is a partial refund of the trading cost you already pay to your broker on every trade. It does not change whether a trade wins or loses — it lowers your cost per trade.
How cashback is generated
When you trade, your broker earns from the spread or commission. An introducing broker (IB) like ShaFX receives a share of that for referring you. A cashback program returns a portion of that share back to you, per lot traded.
What cashback is NOT
It is not profit, not a signal, and not a guarantee. If you trade poorly, cashback will not make you profitable — it only reduces your costs. Treating rebates as a reason to over-trade usually costs more in spread and risk than the rebate returns.
Why it still matters
Over hundreds of trades, lower cost compounds. For an active trader, consistent cashback meaningfully reduces the break-even point of a strategy. The key is that it should be a side benefit of trading you were going to do anyway — never the strategy itself.
