How Much Capital to Start an EA? Size It by Strategy, Not a Flat Number
Capital isn't 'more is better' — it must match the strategy's drawdown profile. Grids need thick funding; single-entry stop systems can be thin. Reference ranges and the math.
"How much to run an EA" has no single answer — because the capital requirement is set by the strategy's drawdown profile, not a fixed number. Under-funding is one of the most common causes of an EA blow-up: not because the strategy fails, but because the account is too thin to survive its normal drawdown.
Core principle: capital must survive the strategy's deepest drawdown
The logic is simple: the account must be thick enough that when its deepest historical drawdown hits, you neither blow up nor panic-intervene. So when choosing an EA, look at its max drawdown first (how to check: verification guide), then size capital from it.
Capital reference by strategy type
| Strategy type | Drawdown character | Capital reference (author-suggested order of magnitude) |
|---|---|---|
| Single-entry + hard SL (breakout/time/scalp) | Realized, bounded | Lower, often $100–$300+ (e.g. TwisterPro, Smart Owl) |
| Trend grid (no doubling) | Floating, moderate | Mid, often $500–$1000+ (e.g. Athena) |
| Grid + martingale (doubling) | Floating, large tail | Thick — low-risk settings often need thousands (e.g. Waka Waka suggests $6,000+ for low risk) |
Note: these are the authors' suggested deposit magnitudes; the product page and official notes govern. The rule: the more a strategy relies on averaging, the thicker the capital — what you're really buying is a buffer to absorb drawdown.
Three easy mistakes
- Running aggressive settings on the minimum deposit: the stated minimum usually maps to the low-risk tier. Aggressive settings need more capital.
- Multi-symbol on one account without adding funds: drawdowns stack across symbols; scale capital by symbol count.
- Borrowing or betting your net worth: leverage always uses money you can afford to lose. This has nothing to do with strategy quality — it's the floor.
How to set your number
(1) After picking an EA, check its max drawdown; (2) choose the risk tier you can sleep with; (3) capital ≥ the author's suggested deposit for that tier, with buffer; (4) go live with a small slice first. Each EA's account-requirements table is in its review (enter via the store, use WELCOME10 for 10% off). Don't want to size and watch it yourself? Managed accounts handle it by risk tier.
Risk note: capital suggestions are references only, not investment advice; leveraged trading is high risk and adequate funding does not remove the chance of loss; past performance does not represent future returns. Only trade with money you can afford to lose.
