Navigating financial transactions on digital trading platforms can be confusing, especially when it comes to depositing funds via bank transfer. One of the most common and secure methods used in the U.S. is ACH (Automated Clearing House) transfers. This guide breaks down everything you need to know about ACH deposits, withdrawal rules, fees, security policies, and more—so you can trade with confidence.
Whether you're new to crypto trading or expanding your funding options, understanding how ACH works is essential for smooth, efficient transactions.
What Is ACH?
The Automated Clearing House (ACH) network is a U.S.-based electronic system that facilitates bank-to-bank money transfers. It’s widely used for direct deposits, bill payments, and peer-to-peer transactions. On trading platforms, ACH allows users to securely deposit U.S. dollars directly from their bank accounts.
ACH transfers are known for being cost-effective and reliable, though they aren’t instantaneous. They go through a clearing process that typically takes several business days, depending on banking and platform verification procedures.

What Is Plaid?
Plaid is a leading financial technology company that powers secure connections between users’ bank accounts and financial apps. When you link your bank account using Plaid on a trading platform, you're authorizing a safe, encrypted data exchange that verifies your identity and account ownership—without sharing sensitive login details.
Plaid supports thousands of U.S. banks and credit unions, making it one of the fastest ways to initiate ACH deposits.
Note: If your bank doesn’t appear in the Plaid interface or fails to connect, this may be due to temporary technical issues on the bank’s end. In such cases, consider using an alternative bank or deposit method.
ACH Deposit Limits: What You Need to Know
Deposit limits vary based on your account history and activity level. These rolling limits are designed to manage risk while promoting responsible trading behavior.
Rolling 10-Day Deposit Limits
- New accounts: $2,000 per 10-day period
- Positive transaction history: $5,000 per 10-day period
- Strong positive history (active traders): Up to $20,000 per 10-day period
These thresholds reset continuously over time and may increase as you build a consistent deposit and trading record.
Single Transaction Limit
You can deposit up to $2,000 at once, though this amount may adjust based on past success rates and platform risk assessments.
Keep in mind: Early crediting of funds is not guaranteed. In some cases, full clearance through the ACH network may take up to 6 business days.
How Long Do ACH Transfers Take?
ACH deposits generally follow a two-phase timeline:
- Clearing Phase (4–6 business days): The funds move from your bank to the trading platform’s banking partner.
- Holding Period (7 business days): After clearance, the platform applies a mandatory hold for security reasons.
This means you cannot withdraw deposited funds for at least 14 business days after initiating the transfer.
Even if technical delays occur, withdrawals become available within 14 calendar days once both banks confirm the transaction.
Why Are ACH Deposits Held for 14 Days?
The 14-day hold serves as a fraud prevention measure. Since ACH payments can be reversed due to insufficient funds or disputes (known as chargebacks), platforms must wait until the reversal window closes before releasing funds.
After the initial 4–6 day clearing period, a 7-business-day hold ensures full settlement and compliance with financial regulations.

Are There Fees for ACH Deposits?
Yes. Most platforms charge a standard fee of $2.99 per ACH deposit. This covers processing costs and helps maintain fast, reliable service across millions of transactions.
There are typically no additional hidden charges, but failed deposits may result in penalty fees (see below).
Can I Link a Bank Account in Someone Else’s Name?
No. For security and regulatory compliance, you can only link a bank account under your own legal name—matching exactly with your verified trading account details.
Attempting to use another person’s account may lead to:
- Transaction delays
- Account restrictions
- Requirement for additional verification documents
Always ensure your personal information matches across all platforms and financial institutions.
Chargebacks and ACH Reversal Policy
While platforms often credit your account instantly upon initiating an ACH transfer, the actual funds aren't secured until the bank completes processing (4–6 business days). If your bank rejects the transfer—due to insufficient funds or cancellation—a chargeback occurs.
In such cases:
- The temporarily credited amount will be removed from your balance.
- A $20 reversal fee may be applied.
- If you've already used the funds to buy other assets, part of your holdings may be sold automatically to cover the fee.
- Accounts cannot carry a negative USD balance.
This policy protects the platform from financial loss due to fraudulent or failed transactions.
My Balance Is Negative – What Does That Mean?
A negative balance usually indicates that one or more of your ACH deposits failed. Common reasons include:
- Insufficient funds in your bank account
- Bank-imposed transaction blocks
- Technical errors during processing
Since these issues originate outside the platform, support teams can’t reverse them directly. However, you can resolve the negative balance by:
- Contacting your bank to understand the cause
- Making a new successful deposit
- Reaching out to customer service for account review
Timely action helps restore normal access and prevents long-term restrictions.
Can I Delete My Linked ACH Account?
Yes. If you no longer wish to use a particular bank account for deposits, you can remove it directly from the platform.
To delete:
- Go to the deposit section
- Open the bank account dropdown
- Select “Delete” next to the linked account
This action only removes the connection—it does not affect past transactions or outstanding balances.
Important ACH Information You Should Know
- Funds may not be credited early if risk systems flag activity or if early credit limits ($2,000 rolling) are exceeded.
- Withdrawals remain restricted until both banks confirm clearance (4–6 days) plus the 7-day holding period.
- In rare cases involving suspicious activity, funds may be held for up to 60 days for investigation.
- Wire transfers are a faster alternative if immediate availability is needed.
Building a strong transaction history increases trust and may lead to higher limits and shorter holds over time.
Frequently Asked Questions (FAQ)
What is the difference between ACH and wire transfers?
ACH transfers are lower-cost and take longer (4–6 business days), while wire transfers are faster (often same-day) but come with higher fees. Wires also don't have post-clearance holding periods on most platforms.
Why did my ACH deposit fail?
Common causes include insufficient funds, incorrect account details, bank-imposed blocks, or technical issues with Plaid integration. Check with your bank for specific error codes or messages.
Can I speed up the 14-day hold?
Not automatically. The hold is mandatory for security. However, long-term users with strong trading histories may request a review for earlier release—though approval isn't guaranteed.
Is Plaid safe to use?
Yes. Plaid uses bank-level encryption and never stores your online banking passwords. It only accesses transaction data necessary for verification.
Will I get charged if my ACH deposit fails?
Possibly. If a deposit results in a chargeback due to insufficient funds, a $20 reversal fee may apply to cover administrative costs.
Can I use multiple bank accounts for ACH deposits?
Yes, as long as each account is under your name and properly verified. You can link and switch between multiple accounts in the deposit interface.
