All trading activity conducted within PropShopTrader OÜ programs is simulated or evaluation-based. Any references to accounts, balances, profits, losses, or performance metrics refer solely to simulated or evaluation results and do not represent live trading in a customer brokerage account.
Bracket orders and short selling for stocks are currently limited due to a technical issue with our execution and data provider (Rithmic).
Some Rithmic-supported platforms may display these features; however, execution may be inconsistent or fail. Rithmic is aware of the issue and is actively working on a fix. These limitations do not prevent stock trading and do not affect buy-only trading functionality.
What is a stock #
A stock is an equity security representing ownership units called shares in a public company. A stock trade is the purchase or sale of a specific number of shares at a price per share.
Core terms #
| Term | Definition |
| Share | The smallest tradable unit of a stock position |
| Symbol | The ticker used to route an order (example: AAPL) |
| Bid | Highest displayed price a buyer is offering at that moment |
| Ask | Lowest displayed price a seller is offering at that moment |
| Spread | Ask minus Bid at that moment |
| Liquidity | Ability to buy or sell a stock without causing large price movement. Stocks with lower daily trading volume (for example under 100,000 shares) may experience higher slippage, partial fills, or poor execution, so traders should use extra caution when trading illiquid stocks. |
| Slippage | Difference between expected fill price and actual fill price |
| Long | Position that profits if price rises |
| Short | Position that profits if price falls (short selling is allowed only for symbols on the Easy To Borrow (ETB) list) |
Commissions for stocks is: $0.002666/share/side
What is ETB (Easy To Borrow)? #
ETB (Easy To Borrow) refers to stocks that are currently available to be short sold based on availability from the market and our data and execution provider.
Stocks designated as ETB may be traded both long (buy) and short (sell).
Stocks not designated as ETB are considered buy-only and may not be short sold.
Important ETB Rules #
- Only stocks listed on the ETB list may be short sold
- Stocks not on the ETB list are buy-only
- For buy-only stocks:
- You may exit a position using the same number of shares or fewer than originally purchased
- You may never exceed the original share quantity when selling
- You can never go net short
- The order would be rejected if you are about to go net short on Non ETB stocks.
- ETB availability may change and is monitored dynamically
- Hedging behavior across positions or accounts is monitored and not permitted
Example #
- ETB stock: A stock appears on the ETB list. You may buy 100 shares or short 100 shares.
- Non-ETB stock: A stock does not appear on the ETB list. You buy 100 shares. You may sell up to 100 shares to exit, but you may not sell more than 100 shares.
ETB Availability Disclaimer #
Short-selling availability for stocks may be temporarily limited due to technical constraints with our execution and data provider (Rithmic). In such cases, short selling may be unavailable even for ETB-designated symbols. We are actively working with our providers to resolve this and will notify traders once full short-selling functionality is restored.
Stock order types #
| Order type | What it does | Primary risk |
| Market | Executes immediately at best available prices until filled | Fill price uncertainty during fast moves or less liquidity |
| Limit (Preferred while trading Stocks) | Executes only at limit_price | Risk of no fill if market does not trade at the limit price |
| Stop | Becomes a market order when stop_price is reached | Can fill far from stop price during gaps or fast moves |
| Stop limit | Becomes a limit order when stop_price is reached, using a defined limit | Can fail to fill if price skips past the limit |
Why stop orders can behave poorly in fast moves #
A stop order becomes a market order once triggered. If price gaps or liquidity is thin, the first available fill can be materially worse than the stop trigger price.
Bracket Orders for Stocks #
Bracket orders and short selling for stocks are currently limited due to a technical issue with our execution and data provider (Rithmic).
Some Rithmic-supported platforms may display these features; however, execution may be inconsistent or fail. Rithmic is aware of the issue and is actively working on a fix. These limitations do not prevent stock trading and do not affect buy-only trading functionality.
What to do instead #
You can place the same risk controls using individual orders:
- One entry order
- One stop loss order
- One take profit order
These order types are fully supported and execute normally during 8:30 – 15:45 EST trading hours. Using individual orders gives you the same position control as a bracket order.
Platform compatibility #
You may trade stocks on any supported trading platform that connects to Rithmic and has stock trading capability.
If your platform supports stocks through Rithmic, you can trade stocks there if they are a part of our supported list. If not, you can use Tickblaze, which is fully supported for stock trading.
Because platform implementations vary, if your platform offers bracket orders for stocks, you should test them with a small position first before relying on them.
