Topstep vs Apex Trader Funding: How to Compare Automation Rules, Drawdown and Payouts

Before you compare fees or profit splits between Topstep and Apex Trader Funding, answer one question: will you place every order yourself? If the answer is no, the automation rules decide the comparison, and they are different at the two firms. Everything else, including drawdown, consistency math and cost, matters, but it comes second.

I'm not going to declare a winner, because both firms change account types, prices and rules, and what applied to one account vintage may not apply to another. What follows is a method for reading their documents, with hypothetical numbers where a calculation helps.

Automation: the rule to read first

Apex explicitly prohibits automated or algorithmic preset bots that place, modify or cancel trades without personal real-time review. The wording is on Apex's prohibited activities page and in the user agreement. Read both for the exact language, since the agreement governs your account. That means I won't describe YMI bots or any other automation as Apex compatible or as an evaluation-passing tool. Manual trading, in which you decide and review each order, is a different thing from a bot, and if a tool in your workflow places, modifies or cancels orders for you, ask Apex support in writing how the rule applies.

Topstep handles this by account product. Whether bot or API use is allowed depends on which product you hold. The TopstepX API article describes API access for SIM, not Live, requires a personal device, and prohibits sending orders through a VPS, VPN or remote server. I wouldn't plan to automate a Topstep Live account. Check Topstep's own help documentation for your product and keep the answer on file.

Drawdown: read the exact mechanics

Both firms use drawdown rules that have varied by product and over time, so avoid shortcuts like 'one locks and the other doesn't.' Find, in the document for your account, whether the limit trails on intraday equity or on end-of-day balance, whether unrealized profit counts, and whether and when the floor stops moving.

The effect is easy to see with a hypothetical $50,000 account and $2,500 trailing limit that counts open profit. A trade that floats to +$800 and returns to flat raises the floor from $47,500 to $48,300, leaving a $1,700 cushion. Under an end-of-day trail, the floor would move only after the close. Which of those you face changes how big you can safely trade, and you can't know it from a comparison article.

Consistency and profit targets

If a rule limits the share of profit from your best day, turn it into a required total. With a hypothetical 30% limit, a $1,400 best day needs about $4,667 of total profit, because 1,400 divided by 0.30 is 4,667. With a 40% limit, the same best day needs $3,500. Check how each firm defines the measure, whether it applies in evaluation, at payout, or both, and what happens if you fail it.

Accounts, contracts and sessions

Each firm sets its own cap on simultaneous accounts, maximum contracts, and whether micros are scaled differently. Look for any rule on news events and any required flatten time. Don't assume sessions and holidays are universal. US equity cash hours are 9:30 a.m. to 4:00 p.m. Eastern, and CME Globex equity futures typically run Sunday through Friday from 5 p.m. to 4 p.m. Central with a daily break, but the CME holiday and product schedule is the reference.

Cost and payouts

List the evaluation fee, resets, activation or monthly fees, and data and platform costs from the current pricing page, on the day you buy. Promotions come and go, so a past discount tells you nothing about today. Add the cost-to-pass math: expected fees per pass equal the fee divided by your chance of passing, which you can't know in advance. Then read the payout terms, including any minimum days or balance, the share structure, and processing times. A funded account is not a live account, and a payout is not guaranteed, so budget as if each attempt could be a total loss of its fee.

Payout taxes are their own question. Money paid under a firm's contract may be service or contract income and not automatically a Section 1256 gain, so ask a tax professional before assuming any particular treatment.

How to choose

If you trade manually and make every decision, both firms are plausible, and the choice comes down to drawdown mechanics that fit your typical trade, the consistency definition you can live with, and total cost. If you intend to automate, start from each firm's written automation rule, for your product, before looking at price. For Apex, that rule prohibits preset bots that act without personal real-time review. For Topstep it depends on the product, and its API article points to SIM only, from a personal device, with no VPS, VPN or remote server.

Whatever you choose, rehearse the workflow in NinjaTrader on a SIM account first, remembering that SIM is not a live-fill test and that 50 SIM trades are not proof of an edge. A manual plan built on fixed reference levels, like the daily KPL levels, is one structured way to practice.
