A Hundred Percent Deposit Bonus: Do the Volume Math
Situation: a broker offers a 100 percent bonus on a 500-dollar deposit, giving you 1,000 dollars of trading balance. The terms say the bonus becomes withdrawable after you trade 30 standard lots, and withdrawing your own deposit before then cancels it.
Compute what it takes. Thirty lots at 0.50 lots per trade is 60 trades. At a 12-dollar cost per standard lot in spread, the cost of trading 30 lots is 360 dollars.
So the net value of the bonus, if you complete the volume with zero trading profit or loss, is 500 minus 360, which is 140 dollars. That looks positive, but trading is not neutral. Sixty trades carry risk and your own edge, or lack of it.
If your expectancy is zero before costs, the costs are the only effect: 140 dollars gain. If your expectancy is minus 0.05R per trade at 10 dollars of risk per trade on a larger size, the loss on 60 trades adds up, and the bonus disappears.
Notice the incentives. The broker earns the spread on 30 lots, whichever way your trades go, and the bonus encourages volume that may exceed your plan.
Also check the fine print on leverage restrictions, maximum lot size, prohibited strategies, and time limits. A condition that voids the bonus after any withdrawal makes your own money harder to access.
The cleaner choice is often to decline the bonus, and keep full control of your deposit.
Practical rule: if the terms require trading more than your plan would, the bonus is a cost.
Exercise: calculate the volume required and the cost in spreads for a bonus offer you have seen.

Fairman, the volume math shows exactly why such bonuses are rarely free. Thirty standard lots on a small account forces a trading frequency or size that most plans would never allow. A good rule for readers: calculate what the volume requirement implies in trades per day at their normal size, and if that number is unrealistic, the bonus is really a condition on the deposit.

Deposit bonuses sound generous. A hundred percent match on a deposit looks like doubled capital. The conditions behind it often make it unusable for a scalper.
Typical clauses include a trading volume requirement before the bonus or profits can be withdrawn, sometimes hundreds of lots. Some bar scalping outright, either by minimum hold time or by excluding trades that last under a set number of minutes. Some cancel the bonus and any related profit if the account is flagged for "abusive" practice, a term that is rarely defined.
Withdrawal restrictions are another catch. Taking out any money can void the bonus, and in some cases the profits earned with it.
A bonus also changes the broker's behaviour. Accounts with bonuses may be routed differently, face wider spreads or be restricted in leverage.
A few questions to ask in writing: what exactly must be done to keep the bonus, what happens to profits if withdrawal happens early, and is scalping allowed.
Most experienced scalpers skip bonuses altogether. A clean account with clear terms is worth more than a larger balance full of conditions.
Has a bonus ever made an account harder to withdraw from?

The volume requirement is where the real cost hides. Thirty standard lots is a lot of trading for a 500 dollar deposit. At 0.50 lots per trade, which is already a large size for a 1,000 dollar balance, it takes 60 trades. At a more sensible size for the account, say 0.05 lots, it would take 600 trades. That volume pushes the trader toward either oversized positions or excessive trading, both of which increase risk. The bonus is structured to generate spread revenue for the broker, and the trader pays for it through costs and the risk of larger losses.

I once took a bonus like this on a small account and the part that hurt was not the volume itself but what it did to my habits. The requirement was 25 standard lots, and I was only comfortable trading around 0.1 per position, so I needed hundreds of trades. About halfway through I noticed I was taking setups I would normally skip just to move the counter forward.
My costs per lot were also higher than the example suggests, because I was scalping through London open when spreads were wider, and the bonus terms excluded trades closed in under two minutes, which cut out many of my best exits. I ended the month with the bonus credited on paper and my own deposit about 15 percent lower than where it started.
Now I read three things before touching any offer: the exact lot requirement, the minimum holding time, and what happens to profits if I withdraw. If any of them clashes with my normal plan, I decline and keep the account clean.

The condition that withdrawing your own deposit cancels the bonus is a significant restriction. It means the 500 dollar deposit is effectively locked until the volume is completed. If the trader needs the money, or loses confidence in the broker, they can't withdraw without losing the bonus, and in some cases, the terms may allow the broker to deduct bonus related profits too. Some regulators, including those applying ESMA rules, have banned or restricted bonuses for retail clients for exactly these reasons. Bonuses are more common at offshore brokers, which is itself worth noting.

It's worth checking how the bonus affects margin and stop out. Some brokers count the bonus as equity for margin purposes, which allows larger positions, but remove it when equity falls to a certain level, which can trigger a sudden stop out. A trader who sees 1,000 dollars of equity may size positions accordingly, then find that after a 500 dollar loss, the bonus disappears and the account is closed out. Reading the terms on how the bonus interacts with margin calls and stop outs is essential before accepting it.

Declining the bonus, as the post suggests, is often the cleaner choice. It keeps full control of the deposit, avoids the volume pressure, and removes the conditions that complicate withdrawals. A trader who wants to trade with 1,000 dollars can deposit 1,000 dollars, with no strings attached. Has anyone here accepted a deposit bonus and later found the conditions harder than expected? It would be useful for newer members to hear what happened, especially with the volume requirement and any problems when trying to withdraw. Real experiences are often more persuasive than the arithmetic.
