Rebates quietly change what a good strategy looks like

[Shadow Trader]

Many brokers and introducing partners offer a rebate: a cash payment per lot traded, regardless of whether the trade wins or loses. For a scalper doing 50 or 100 lots a month, the sum is not trivial. A rebate of 3 dollars per lot on 100 lots adds up to 300 dollars.

On the surface this is a pure benefit. It reduces the effective cost per trade, and in some cases turns a marginally losing system into a marginally winning one.

There are side effects that rarely get discussed. A rebate rewards volume, which nudges behavior toward more trades. The temptation to place extra trades just to collect the payment is real, and it can damage the quality of entries.

Another issue is the source. Rebates usually come from the broker's markup. The spread or commission on a rebated account might be higher than on a direct account, so the net saving is smaller than it looks. A proper comparison means calculating total cost per lot after the rebate on both versions of the account.

Then there's the matter of conditions. Some rebate programs have minimum volumes, delayed payment, or clauses that cancel the rebate for trades held less than a certain time, which is exactly what scalpers do.

The honest test is simple: calculate the net cost per round-turn lot, spread plus commission minus rebate, across a month of actual trades. Only that number allows comparing offers.

Tracking helps. A small spreadsheet with a row per month, listing the lots traded, the gross rebate, the extra cost from any spread markup or commission difference, and the net figure, shows the real value.

Sometimes the net is solid. A rebate of 4 dollars per lot against an extra cost of 1 dollar is a good deal. Sometimes the extra cost eats it entirely, as when a "rebated" account has a spread 0.5 pips wider, worth 5 dollars per lot.

Another check is how the rebate is paid. Some partners pay weekly, others monthly, others only above a minimum balance. A rebate that is stuck behind a payout threshold effectively gives the partner an interest-free loan.

How much of the headline rebate survives once it's compared against the full cost of the account?
