Odysseus Trade — position size limiter for Bybit futures
Odysseus
Position size limiter · Bybit futures

You said $5,000 tops. Your hand typed 25,000.

Three seconds later the position is back to 5,000. Odysseus stands between you and the exchange and trims whatever goes above your ceiling — even once the button has been pressed.

One week free · no card · you create the key without withdrawal rights — no one can move money with it

Odysseus is a desktop app: it watches your account on macOS or Windows. It will not run on a phone — open this page on a computer.

Bybit USDT perpetuals only. Spot, inverse contracts and options are not limited.

Одиссей, привязанный к мачте, проплывает мимо сирен

Odysseus the trader knew he would not resist the song. So he tied himself to the mast — beforehand.

The Odysseus window: position ceiling, entry ceiling and the intervention log
How it works

Two numbers — and what they mean in your own money

Position ceiling

The most that may sit in the market at once. Go in bigger and the excess is trimmed within seconds.

Single-entry ceiling

The most you may add in one go. Three entries of 100 under a 100 limit is fine. One entry of 300 is not.

Market entries are caught too

A resting order is shrunk before it fills, so you pay no fee. A market order can't be intercepted, so the excess is trimmed right after it lands.

You set the numbers as leveraged volume — the same figure as the exchange's Value column. The app converts it on the spot: $5,000 at 10× is $500 of your own money.
Sound familiar?

Accounts don't die from bad analysis. They die from size.

All in

The setup looked perfect, so you went in three times your usual size. Price moved two percent against you and a month of work was gone in one trade.

Averaging down

By the third add the size had quadrupled, and the stop you had planned now cost half the account.

A blown prop-firm account

The firm's daily limit gone in a single trade. The strategy held up — the size didn't, and the challenge fee went with it.

Willpower works while you're calm. Odysseus doesn't get tired, doesn't argue and doesn't make exceptions.

Straight talk

Yes, this is an app with access to your exchange. So, four things up front.

One switch turns it off. Every intervention is a line in the log: what was trimmed, why and by how much.

01

A key with no withdrawal rights

You create it yourself and leave the withdrawal box unticked. Even if the key leaks, moving money off the exchange with it is physically impossible.

02

It can do exactly two things

Reduce a position and reduce your own resting order. It cannot open a trade, flip a position or cancel a stop-loss — protective orders are detected separately and never touched.

03

Keys never leave your computer

They live in the system keychain. The server holds only your subscription and access code; no keys are stored there.

04

It doesn't pretend to cover everything

Only Bybit USDT perpetuals are limited. Spot, inverse contracts and options are invisible to the app — and it says so in the window itself, not in small print at the bottom of a website. Other exchanges are planned.

Price
$10per month

It's cheap because the product shipped days ago and I need your complaints more than your money. As it grows features the price will go up — whoever came early keeps the old one.
