Your trading rules, enforced.

Follow your rules. You’re done for today.

You already know your rules. Tradeblockr holds you to them. Set them before the session, and Tradeblockr cancels any order that breaks them. When you hit your limit, it closes your position and locks you out until the next session.

You’re done for today.

This is what Tradeblockr shows when you hit your limit. Your position is closed, and every new order is cancelled until the next session. Quitting Tradeblockr doesn’t end it.

Unlocks at midnight ET.

How it works

  1. 1

    Set your rules

    Max trades per day. Max risk per trade, with a stop required. A daily loss limit. A trading window. A cooldown after a loss. Lock them before the open so you can’t loosen them mid-session.

  2. 2

    Tradeblockr cancels what breaks them

    An order with no stop, too much size, outside your window or right after a loss is cancelled, and you see which rule it broke.

  3. 3

    When you’re done, you’re done

    Hit your limit and Tradeblockr closes your position, locks you out until the next session, and cancels every new order until then.

The software

See what Tradeblockr did, and why.

Your trading window is a bar from the open to the close. Every order Tradeblockr cancels shows up on it as a red dot, and the log underneath names the rule that order broke.

Today screen: the trading window as a timeline with cancelled orders marked, tiles for orders stopped, risk blocked, today's P&L and trades left, a streak card, and the limits including a daily loss limit.

Set your rules, then lock them.

Choose your max trades, your max risk per trade, a daily loss limit, your trading window and your cooldown after a loss. Once you lock them you can't change them until midnight ET, so you can't loosen them in the middle of a bad session.

Rules screen: 3 trades a day, 15 minute cooldown, 9:30 to 11:00 ET window, 1% max risk on a $50,000 account which works out to $500 per trade, a $500 daily loss limit, locked until the next session.

Keep track of the days you stuck to them.

A session where Tradeblockr never had to step in is a blue square. A session where it did is red. Your streak counts the blue ones in a row, and the last twelve weeks sit on one screen.

Progress screen: this week's clean days and orders stopped, your streak and best streak, and a twelve-week calendar with a blue square for each session you followed your rules and a red one where Tradeblockr stepped in.

Screens show example data.

Common questions

Does Tradeblockr place trades?

No. Tradeblockr only cancels orders that break your rules and closes your position. It can’t open a trade or add to one.

Which platforms does it work with?

We’re building for Tradovate, Rithmic and NinjaTrader. Support is planned, not available yet, and Tradeblockr isn’t affiliated with any of them. Some prop firms limit third-party tools, so check your firm’s rules before you use it.

What happens when I hit my limit?

Tradeblockr closes your position, locks you out until the next session, and cancels every new order until then. Quitting Tradeblockr doesn’t end the lockout.

Can I change my rules during the session?

No. Set them before the open and lock them. Once locked, they stay that way until the next session.
