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 typeDrawdown characterCapital reference (author-suggested order of magnitude)
Single-entry + hard SL (breakout/time/scalp)Realized, boundedLower, often $100–$300+ (e.g. TwisterPro, Smart Owl)
Trend grid (no doubling)Floating, moderateMid, often $500–$1000+ (e.g. Athena)
Grid + martingale (doubling)Floating, large tailThick — 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).

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.
