How to Run Multiple Prop Firm Accounts With One Pine Script

Running 3–10 evaluation accounts on a single Pine Script isn't a workaround — it's the standard approach for systematic traders managing pass-rate variance. Here's the exact setup, the cost math, and which firm combinations work best.

Why traders run multiple prop firm accounts

A single evaluation has a known pass probability, and it's rarely close to certain — even a well-backtested strategy with a genuinely strong historical edge fails a meaningful share of individual attempts to variance alone: an unlucky stretch of sessions, a strategy-unfriendly market regime during the eval window, a stop hit on a fluke gap. Running one account at a time means being entirely at the mercy of that variance on every attempt.

Running several accounts at once changes the math. If a strategy has, say, a 55% chance of passing any given evaluation, running five at once means statistically expecting two or three passes in that batch — and those funded accounts start generating payouts while the failed attempts get replaced with fresh ones. Time to funding compresses from a coin-flip single attempt into a much more predictable multi-attempt process.

Traders who've been doing this for more than a few months commonly run at least three accounts at once; those who've systematized the process often run six to twelve. It isn't an edge case — it's closer to the industry norm among serious systematic prop firm traders.

Is running multiple accounts allowed?

Yes — every major US futures prop firm permits it. Apex Trader Funding, Topstep, MyFundedFutures, and Tradeify all allow traders to hold several evaluation accounts at once and to run identical strategies on all of them. There's no rule against automating across multiple accounts and no requirement to vary the strategy between them.

The nuance sits on the funded side: some firms cap how many funded accounts can be simultaneously active. These caps are typically generous and rarely bind for an individual trader, but confirm the current funded-account policy directly with each firm before scaling past 5–6 funded accounts.

Prop firm policies evolve. Verify multi-account rules directly with each specific firm at the time of setup — the general shape described here reflects the industry standard, but exact terms shift.

The setup: one script, one alert, many accounts

The architecture is simpler than it sounds — no need for multiple TradingView subscriptions, multiple script licenses, or multiple chart windows. One chart, one alert, and one TradersPost account configured with several broker connections covers the whole setup.

A Pine Script runs on a single TradingView chart. When it generates a signal at bar close, TradingView fires one alert carrying a JSON payload. TradersPost receives that single webhook call and routes the same order to every broker connection configured — each one pointing at a separate prop firm account at Tradovate or Rithmic. One signal, multiple simultaneous executions.

Step-by-step setup

Set up one TradingView chart with the Pine Script. Apply it to a single continuous-contract symbol (ES1!, NQ1!, MES1!, or MNQ1!) and confirm signals and alerts are generating correctly on bar close. This chart is the single source of truth for every downstream account.
Create one TradingView alert on the strategy. Set the condition to the strategy's order fills, frequency to firing once per signal, and the webhook URL to the TradersPost endpoint. One alert fires once per signal — TradersPost handles the fan-out from there.
Create a separate broker connection per account in TradersPost. Three Apex accounts and two Topstep accounts means five connections, each authenticated to its own sub-account at Tradovate or Rithmic. TradersPost supports mixing brokers, so firms on different platforms can sit in the same setup.
Create a linked automation for each account. Configure each with its own ticker, order type, and contract quantity, then link all of them to the same webhook. A single incoming alert fires an order through every linked automation at once, each hitting its own account.
Set position sizing per account independently. A 50k account near its drawdown floor might run 1 contract while an account with a comfortable cushion runs 2 — sizing per account is the main risk lever when running several at once.

Risk management across multiple accounts

Running several accounts doesn't compound personal financial risk — each evaluation fee is a known, capped cost. It does introduce correlated failure risk: if every account runs the same strategy on the same instrument at the same time, one bad session can threaten several accounts on the same day.

The practical mitigation is position sizing. Keep per-trade risk on each account small enough that even a worst-case losing session stays well inside its daily/drawdown limit. Five accounts at one MES contract each with a modest stop keeps a full losing day's cost, per account, well inside any 50k account's daily limit.

On execution variance: TradersPost fires orders to each linked automation sequentially rather than simultaneously. On a liquid instrument like MES during regular hours, this happens in milliseconds and the price impact between the first and last account filled is typically negligible over a full session.

Which prop firms to stack

The most effective approach diversifies across firms with different drawdown models, so a specific kind of market behavior — a volatile session that spikes and fully recovers, for example — doesn't trip the same mechanism on every account at once.

Firm	Drawdown Model	Why Stack It
Apex Trader Funding	Intraday trailing	No daily loss limit at any size — the widest cushion for a strategy with occasional larger drawdown sessions.
Topstep	EOD trailing	Intraday spikes don't move the floor — best for strategies with intraday volatility that recovers by the close.
MyFundedFutures	Static	Winning runs never tighten the trail — best for strategies that build a large cushion early.
Tradeify	EOD trailing	The Growth path carries no hard daily limit — a fourth distinct drawdown exposure profile in the stack.

The cost math on account stacking

The economics hold up when the numbers are run honestly. A single $50k evaluation across these firms is typically priced somewhere in the low hundreds at full price, often discounted meaningfully below that. Running five concurrent evaluations lands in the mid-hundreds-to-low-thousands in fees — and at a 55% pass rate, that spend is expected to produce two or three funded accounts.

Two funded $50,000 accounts generating a combined few thousand dollars a month in payouts (achievable for a consistent systematic strategy) recoup that evaluation spend within the first month or two of funding. Compare that to buying a funded account outright on a secondary market — account stacking is meaningfully more capital-efficient for a strategy with a genuine, if imperfect, edge.

Pass rates are strategy- and market-regime-dependent, and evaluation pricing shifts with promotions. The figures above are illustrative rather than reconciled firm data — verify current pricing directly with each firm before budgeting a stacking plan.

FAQ

Is it allowed to run multiple prop firm accounts?

Yes. Every major US futures prop firm — Apex, Topstep, MyFundedFutures, and Tradeify among them — explicitly allows traders to hold multiple evaluation accounts at once and to run the same strategy across all of them. Some firms cap how many funded accounts can be simultaneously active, so verify that specific limit directly with the firm before scaling past a handful of funded accounts.

Do I need to buy a separate Pine Script for each account?

No. One TradingView chart running one Pine Script sends one alert per signal. TradersPost receives that single alert and fans it out to as many broker connections as are configured — each pointed at a different prop firm account. One script, one TradingView alert, and one TradersPost subscription can cover every account at once.

Will every account execute at exactly the same price?

Not quite — TradersPost routes orders to each connected broker account in rapid sequence, so expect roughly 1–3 ticks of variance between the first and last account filled. On liquid instruments like MES and MNQ during regular hours, that variance is typically small and doesn't meaningfully change strategy performance across the portfolio of accounts.

Which combination of prop firms is best for account stacking?

Apex Trader Funding + Topstep + MyFundedFutures is a popular three-firm combination because each uses a different drawdown model — intraday trailing, EOD trailing, and fully static, respectively — spreading risk across rule structures so a single kind of market move can't threaten all of them at once. Adding Tradeify extends that diversification with a fourth profile.
