A journal that reconciles
Import a statement or connect an exchange read-only, and every fill is folded into positions with fees included. Quantities and prices are kept as fixed-point decimals, so the numbers still add up after a thousand trades.
Closed testing
Trade with your own numbers, not somebody’s screenshot.
Trade73 is a trading journal and strategy engine for crypto spot markets. It reconciles what you actually traded, tests strategies with the fees left in, and runs them on paper before it runs them on anything else.

Trading carries risk and most strategies lose money. Trade73 does not predict markets and makes no claim about returns.
Track
Every fill, reconciled with fees.
Analyze
Backtests with the costs left in.
Automate
Paper first, then your own keys.
Grow
Or find out early that it does not.
Your funds never leave your exchange
Trade73 holds no money and no coins. It connects to your own Binance account with a key you create and can revoke, and it places orders there — your balance stays where it already is, under your own login.
A key with withdrawal permission is refused at the door, not merely unused. There is no deposit address anywhere in this product because there is nowhere for a deposit to go.
Keys are encrypted per account and never shown again after you save them.
What it actually does
Backtests with the costs left in
Every strategy replays over real candles with the exchange fee, slippage on each fill, position sizing and the stop loss applied. The same function that decides in a backtest is the one that decides live — there is no second implementation to drift.
Paper first, then live
A bot runs on paper against live prices for as long as you want. Going live changes one thing: which class places the order. Nothing about the strategy, the sizing or the risk checks is different.
Every decision, written down
Not just the trades. Each tick records what the bot saw and why it did nothing, so “why has it not bought” has an answer you can read rather than infer.
It will tell you when a strategy doesn’t work
Ten strategies ship with Trade73. Every one carries, in its own words, what it is bad at and what the measurements actually said — including the ones that were unflattering.
One of them was a pullback strategy. Backtested across three markets it took 828 trades and won 8% of them, because its entry condition and its exit condition were the same line: half its positions were opened already satisfying their own exit.
It was removed from the catalogue, and the migration that removed it says why. Its replacement is honest that it fails an out-of-sample check.
A backtest here applies the exchange fee, slippage on every fill, position sizing and the stop. A strategy that only works without those is a strategy that does not work, and this is built to say so before your money finds out.

Bring your history
Upload a statement, or connect a read-only key and let it sync.
Test an idea properly
Pick a strategy, set its parameters, and replay it over years of candles with costs.
Run it on paper
Live prices, no money. Watch what it does and what it refuses to do.

Trade73 is in closed testing
A small group, watched closely, while the engine runs other people’s money for the first time. If that is interesting to you, talk to the people building it.
