A favorite hook of the 20-pip challenge is "start with $20". You can — but there are real reasons to think carefully about your starting balance. Here's how to choose.
The appeal of starting tiny
A small start is psychologically easy and limits the cash at risk. If the whole point is to prove a strategy on money you can afford to lose, a small live account does that.
The minimum-lot problem
Here's the catch nobody mentions. Brokers enforce a minimum lot size, usually 0.01 (a micro lot ≈ $0.10/pip). On a very small balance, the lot size the sizing formula asks for may be below that minimum, forcing you to trade larger than the challenge intends. That means:
- your real risk per trade is higher than the rules call for on the lowest levels;
- the early rungs of the ladder are the most fragile, not the safest.
A slightly larger starting balance (so your computed size sits comfortably above 0.01) makes the early levels behave the way they're supposed to.
A practical way to choose
Ask three questions:
- What can I afford to lose entirely? Assume the worst — that's your ceiling. Never use rent or savings.
- Does my computed lot size clear the broker minimum at level 1? If not, the account is too small to follow the rules cleanly.
- Will small swings rattle me? If watching a tiny balance tempts you to override the system, a size that feels "boring" is actually correct.
For many people a starting balance in the low-hundreds threads this needle: small enough to risk, large enough to size properly.
Demo first, always
Before any of this, run the challenge on a demo account with your intended starting balance. You'll see exactly how sizing behaves at level 1, how often it trades, and how drawdowns feel — without risking a cent. See how to test on demo.
Bottom line
There's no magic number, but "as small as possible" isn't automatically best — the minimum-lot problem makes ultra-tiny accounts riskier per trade, not safer. Pick a balance you can afford to lose, confirm your sizing works at level 1, and remember the challenge is high-risk with no guaranteed outcome.
