Ninja Trades — Structure-first crypto signals
No trade is a signal too.
Two charts. One honest answer.
Upload your 4H chart
This gives Ninja Trader the bias and all key structural levels — swings, ranges, EMA reclaims.
Upload your 5m or 15m
This is the trigger only. Entry lives on the LTF, but targets and stops come from the 4H.
Signal or NO TRADE
You get a copy-pasteable card — or an honest NO TRADE with levels to watch. C-grade never gets dressed up.
Discipline the model can't shortcut.
Invalidation-first stops
Structural stop first, then a realistic entry, then targets. Never shrink the stop to save R:R.
4H bias veto
Ranging 4H = NO TRADE, no matter how clean the 5m looks.
Cost-floor gate
TP1 must be ≥ 0.42% from entry to survive taker fees round-trip.
Leverage is derived
Highest rung whose liq sits well beyond your stop — capped at 20×. Never a default.
This is what you copy into your group.
Run the risk math before you click buy.
Position size & liquidation calculator
Enter account, risk, entry and stop. Get position size, the highest leverage rung that keeps liquidation clear of your stop, an estimated liquidation price, and a pass/fail on the 0.42% cost floor and R:R gates — the same rules the signal engine uses.

Straight answers before you sign up.
Are crypto signal services worth paying for?
Only when they filter for a real edge and tell you when to stand down. Ninja Trades reads your own two charts, builds the trade backwards from invalidation, and returns an honest NO TRADE when the 4H is ranging or the target can't clear fees.
Which timeframes do I upload?
One 4H chart for bias and structure, plus a 5m or 15m chart as the trigger. Entry comes from the lower timeframe; stops and targets always come from 4H structure.
Does it ever tell me not to trade?
Yes, and that's the point. A ranging 4H vetoes the setup, a TP1 closer than 0.42% from entry fails the fee cost floor, and a C-grade idea is never dressed up as a signal. You get the levels to watch instead.
Is Ninja Trades free?
Yes. Create a free account and generate signals up to the daily fair-use cap (10 per 24 hours by default). Paid tiers with higher limits are planned, but the core generator is free to use.
Do you connect to my exchange account?
No. There are no API keys and no exchange permissions. You upload chart screenshots, and your charts and journal stay tied to your own account.
How is leverage decided?
It's derived, never defaulted. The engine takes the highest common rung (1–20×) whose estimated liquidation still sits comfortably beyond the structural stop. You can check the same math yourself with the free position size calculator.
Which pairs and markets does it work on?
Any crypto perpetual futures pair you can screenshot — majors like BTC and ETH work best because their 4H structure is cleaner and liquidity is deeper.
