⚡ The Trading tab
This is the app's trading floor: the live signal feed, and for
each signal, the ability to buy in one click — without ever leaving the page,
and without ever handing your keys to anyone.
Why this tab exists
A signal is only worth what you can do with it, fast. Without this tab, the journey would be:
receive the alert → copy the mint address → open a DEX → paste → configure → sign. Every step
costs seconds, and in memecoins seconds cost percents. The Trading tab, titled
“Trading assisté” (assisted trading), reduces all of it to: see the signal →
pick an amount → sign in Phantom.
The signal feed
The main column shows signals as they arrive — the same ones as on Telegram, at the
same moment: web cards and Telegram cards are generated from the same stream. Each card
in the feed carries what you already know if you've read
the SIGNAL card page: the score, the risk, the
Mastermind analysis, the exit strategy.
- “Analyse Mastermind en attente…” (analysis pending) — the signal has
arrived, the analysis is being written: it appears as soon as it's ready.
- The re-evaluation badge — if the same token signals again a few hours
after being broadcast, the app doesn't create a duplicate: the existing card carries a
badge indicating that Mastermind re-evaluated the analysis and the score.
- “DÉJÀ EN PORTEFEUILLE” (already in portfolio) — you already hold this
token: the app reminds you so you don't double a position by accident.
Buying in one click — the full journey
- Connect your wallet (button top right): Phantom recommended, MetaMask
supported. Connecting gives the app NO power over your funds — it only allows it to
propose transactions for you to sign.
- Click the signal you're interested in: the buy panel opens (“↩ Retour”
to go back to the feed).
- “Tu dépenses (SOL)” (you spend): type your amount or tap one of the
quick-amount chips. This is the TOTAL amount you commit.
- Slippage: percentage chips and a fine slider. It's the maximum price gap
you accept between the quote and the execution — see the box below, it's THE setting that
protects your buy.
- “Obtenir devis” (get quote): the app queries Jupiter (Solana's price
aggregator) and shows the details — tokens received, price impact
(highlighted orange above 2%), platform fee according to your tier.
- “Exécuter” (execute): the transaction is built server-side, UNSIGNED,
then Phantom opens — “Approve in Phantom…”. YOU sign. “Swap executed!” appears with the
link to the transaction on Solscan: on-chain proof, not an interface's promise.
Slippage in 30 seconds
On a micro-cap, the price moves between your quote and your execution. Slippage too low → the
transaction fails (you only lose network fees); too high → you accept buying much more
expensively than planned. The app proposes suitable values; if your transactions fail in
bursts on a very hot token, go up one notch — knowingly.
Price impact ≠ slippage
Price impact is how much YOUR order moves the market (a function of
liquidity);
slippage is the extra tolerance you accept on top. High impact on
a small amount = tiny pool: that's a serious warning, not a formality.
What this tab will never do
- Buy without your signature. Every purchase goes through your wallet. Your
private key never leaves your device — the app is 100% non-custodial.
- Choose for you. The signal informs, the score compares, the analysis
explains — the decision and the amount remain yours.
Using it well
- Set your per-trade budget BEFORE opening the tab — and respect the
suggested size on the cards.
- Check the price impact on every quote — it's your real-time liquidity
gauge.
- After buying, go to Positions:
that's where the rest plays out (stop-loss, take-profit, exit).
