Grand Capital runs several ongoing promotions rather than a single sign-up bonus. The 40% deposit bonus matches qualifying deposits of $100 or more with bonus credit, up to a lifetime cap of $20,000. That cap is not realistic for most retail traders: the bonus only converts into withdrawable personal funds at a rate of $3 per standard lot traded, meaning freeing the full cap would require thousands of lots. Profit generated while trading is withdrawable, but each withdrawal cancels 40% of the withdrawn amount from the remaining bonus balance, and the credit period runs up to three months (extendable to six with a further deposit).
A separate $500 no-deposit bonus credits new, verified clients with trading capital and no deposit required. The bonus itself can never be withdrawn. Traders get 7 calendar days to generate profit, and cashing out that profit requires two things: heavy trading volume (1 standard lot per $5 of profit, or 100 lots per $5 on a Micro account) restricted to specific forex instrument groups, and depositing personal funds equal to or greater than the profit amount within the same 7-day window. Partial withdrawal of profit is not allowed. In practice this makes the $500 figure closer to a short trading contest than free money.
Grand Capital also runs Payback, a per-lot cash rebate for active Standard-account traders that pays $0.50 to $1.50 per standard lot depending on a trading-streak tier (Bronze, Silver, Gold). Unlike the deposit bonuses, Payback cash is real money with no turnover requirement and can be withdrawn immediately. The catch is that the top $1.50 rate requires 31 or more consecutive trading days, and the tier decays if a trader skips days, so sustaining the headline rate takes ongoing daily activity.
