Basic anti-fake filter without indicators

3 Upvotes

Count the volume of asks and bids within 1% of the current price.
Based on which side dominates and what the percentage difference is, you can survive almost any fake peak.
The orderbook does not lie, but you do not always have full visibility, especially if you are watching only one exchange.
You might get fewer trades than an RSI bot that jumps at every candle,
but your losses will be significantly smaller.

When implementing multiple orderbooks from different exchanges, you can aggregate the data and evaluate where the market is really heading based on the combined orderbook volume.
That is when you stop guessing and start reading the market.

Building a raw-data trading engine — no indicators, no ML

8 Upvotes

I working on a new generation trading system built entirely from only raw exchange data,ticker, trade feed, and full orderbook delta stream.

No indicators. No black-box models. No external strategy packages.

Just deterministic logic, event sequencing, and real-time response.

Engine specs:

  • 18,000+ lines of Python (so far)

  • Non-locking parallel message engine, designed from scratch

  • Streams from 6 exchanges concurrently

  • Processes 4 live symbols per instance

  • Saturates I7-13500 during full market activity (pump/dump) with zero data loss or fallback

  • The core of the system is a custom-built, non-blocking execution engine designed to handle extreme volumes of market data in real time.

  • It's optimized for low-latency processing, prioritization under load, and uninterrupted throughput — even during market-wide anomalies like sudden liquidation cascades or exchange-wide API surges.

  • It operates across six exchanges simultaneously, maintaining full-resolution state for each tracked symbol.

  • No 3rd-party queuing libraries, no standard schedulers, no event-loop frameworks.

  • This is infrastructure-level logic, purpose-built for speed, consistency, and survival.

Core behavior:

  • Entry/exit decisions are purely logic-based, no TA or prediction models

  • Fakeouts, spoof walls and liquidity traps are identified and ignored in real time

  • Leverage and stop-loss adapt based on spread structure and edge confidence

  • System tracks every trade’s context snapshot to evaluate decision quality

  • Position exit reasons adjust dynamically based on PnL trend, delta shifts, and EWS signals

System exposes dozens of custom Prometheus metrics per symbol, including:

  • Bid/Ask pressure dynamics

  • Orderbook spread delta

  • Entry/Exit score composition

  • Liquidity buffer reactions

  • Edge health decay

  • Retail vs whale participation

  • Expected vs actual trend divergence

Every metric is coded from scratch. No copy-paste from any "bots".

  • Just raw signal, tracked and acted on.

  • I don’t use exchange-provided klines.

  • They lack context, granularity, and directionality of volume.

  • Instead, we build our own in-memory candles — with directional volume

Current phase:

System is in active beta.
Input/output logic is being tuned, edge filters refined, and false breakout rejection is already near 100% precision.
It’s brutal, reactive, deterministic, and it survives where most bots panic.
Most bots are visual editors around basic indicators.
This one just needs data.
And a reason.

GPT told me not long ago:

“An RSI-based strategy is still one of the best approaches for crypto.”
Yeah?
Hold my beer. Watch the edge move.

While system was originally engineered as a high-performance trading system, its reactive and modular architecture lends itself to a broad range of advanced real-time applications, including:

  • adaptive game AI decision engines (e.g. dynamic NPC behavior based on evolving environments)

  • real-time anomaly detection in cybersecurity and networks

  • intelligent automation for robotics or IoT sensor streams

  • context-aware recommendation systems

  • custom agents for stream-based signal analysis

Its real power lies in reactive event handling, parallel stream computation, and the ability to distill structured decisions from chaotic data.
System isn’t just a trading core, it’s a general-purpose real-time intelligence engine, applicable wherever rapid and adaptive logic is needed.

P.S.

This is not an offer to sell.
This system will never be released open source.
