AERRO TRADER · HOW IT WORKS
The engine’s call, placed from your own device.
It hears the engine’s callout the second it lands, puts it through thirty-three rules, sizes it to your account, brackets it, sends it to your firm from the phone or the tab you hold — and manages it to the exit, writing down every decision on the way.
INSIDE THE MONITOR
Ten parts between a callout and a fill.
The runner is the tab on your screen. Take the monitor apart and this is what is inside it — every part a rule you can read in plain words, every decision it makes written down. Keep scrolling: it comes back together, and each part shows itself on the screen.
01 · THE CALLOUT
The engine calls it. The runner takes it.
A callout is the engine’s own row: the market, the side, the entry, the stop, the target and the setup that fired — graded in public whether anyone took it or not. The runner hears it the second it lands.
- →AERRO’s setups, the books’ lanes, or setups you built yourself
- →A callout older than a minute is left alone — nothing is chased
- →The record on the card is the engine’s, never a promise
02 · THE GATES
Thirty-three ways to say no.
Before a single order leaves, the callout is put through every rule you set and every rule the runner keeps for you — the switch, the window, the setup, the score, the market, the daily stop, the day’s count, one position per symbol, the firm’s maintenance switch. A refusal is written down like a fill.
- →Your window in New York time; your markets; your setups
- →One position per symbol — the open trade is respected
- →The daily stop ends the day; nothing re-arms it
03 · THE SIZE AND THE BRACKET
Sized to your account. Bracketed before it leaves.
Risk a percent of the account, a fixed count, or the size your firm’s tier calls for — a 150K trades a book in one mini, a 50K in three micros, the same stop distance either way. The stop and the target ride the order as one bracket.
- →The ORB book risks 0.67% of the balance: a 150K’s $1,005 buys one mini on a 46.5-point stop ($930); a 50K’s $335 buys three micros
- →Stops on by default — switching them off is the deliberate act
- →A 50K is sized like a 50K whatever the saved settings say
04 · YOUR DEVICE, YOUR KEY
Nothing leaves the device you hold.
The order goes to your firm from your phone or your own browser tab — the key in the phone’s Keychain or sealed in the browser, never on a server of ours. Topstep through its API key; every Tradovate, TradeSea and WealthCharts firm through their own sign-in; Sierra Chart on your PC for Rithmic.
- →No server of ours ever holds a prop key — the firm’s rule and ours
- →The connection is written down; the key never is
- →Your own brokerage account can run on AERRO’s runner if you choose
05 · THE APPROVAL
You decide. First answer wins.
With approval on, every order is a card — the market, the side, the size, the levels and a thirty-second clock — on every device you are signed into. Face ID on the phone, a click on the desk, a hold on the lock screen; the first answer settles it everywhere.
- →On by default; fully unattended is the setting you opt into
- →The lock screen: the engine asks, your phone places on the tap
- →A dry run writes the same card and moves no money
06 · THE MANAGEMENT
Managed to the exit, from your fill.
The engine’s stop moves are anchored to the price you actually filled at — never to the callout’s — and breakeven covers the fees. Your own dragged stop or take-profit moves the bracket at the broker. The runner follows the engine out, flattens at the time you name, and the daily stop stands over it all.
- →Breakeven is entry plus the round trip plus a tick — never a loss
- →Flat by 3:55 PM ET if you say so; the equity guard if you say so
- →A stop is never loosened to chase a good fill
07 · THE LEDGER AND THE MIRROR
Every decision, written down. Every runner, on your phone.
Placed, refused, closed — each with its why, the levels, the time. The desk tab heartbeats; the phone sees every runner you have up, steers it, and reads the day book per account. A blown account is a life that ended, not a number that carries.
- →The why beside every row, refusals included
- →The day’s P&L is the account’s — one account at a time
- →Arm, disarm, flatten from the phone; the tab obeys
08 · THE BOOKS
Pick a book. Its record is on the card.
A book is the whole stack configured one way — the markets, the setups, the window, the caps, the sizing. Funding · Base, RTY scale, Extended · V2, V6, AERRO ORB, NQ Trend Day, Follow the owner’s hand. Every card carries its own 90-day figure with the basis named, red ones included.
- →The grader’s fills at one account’s size — not money anyone was paid
- →The nightly walk rewrites every card; a red book stays red on its card
- →Switch books in one tap; the settings move together
YOURS TO SET
Every knob is yours. The defaults are the careful ones.
A fresh runner is a practice run that asks before every order and puts a stop on every entry, and trades nothing until you name the markets and the setups. Each setting is a line in your configuration — change it on the phone or the tab, and the runner reads it on its next pass.
WHAT IT WILL NEVER DO
Place an order from a server of ours on a prop account.
Your firm’s rules say the order originates on your device; so do ours. The runner is the phone or the browser tab you hold.
Promise a win rate.
Every book’s card carries the grader’s record over a named window, red ones included. A runner realises 60–80% of a walk, and the card says so.
Hold an unprotected position by default.
Stops are on. Switching them off is the deliberate act, with the disclaimer in front of you.
Automated trading on your own account, under your settings, at your risk. AERRO is a tool, not a broker or an adviser; it is not liable for trading losses or for anything your firm decides about your account — a suspension or a ban for automation included.
