The Technology Stack

The Fortress.
Your data deserves it.

SHA-256 fingerprinting, 34-digit decimal math and AES-256-GCM encryption are not marketing copy — they are why your P&L is accurate and your secrets stay secret.

Core pillars

Three guarantees the data makes to the trader.

Integrity

Every trade gets a SHA-256 fingerprint derived from symbol, prices, quantity, close time and account salt. Duplicates are mathematically impossible — not just filtered.

Precision

A 34-digit Decimal engine handles every asset class natively. Forex pips, futures ticks, crypto decimals and fee drag are computed without floating-point error accumulation.

Privacy

AES-256-GCM encryption protects every secret at rest. API key lookup uses SHA-256 hashing — the raw key is never retrieved for comparison.

SHA-256 Trade Fingerprinting

A duplicate trade has nowhere to hide.

Fingerprints combine symbol, side, entry price, exit price, quantity, close timestamp and account salt. The same trade from two accounts is correctly identified as two distinct records — and a re-import of the same file is safely suppressed.

1
Build the fingerprint

Seven fields hashed into a canonical string per trade per account.

2
Hash with SHA-256

Digest stored in integrity ledger. Raw import string never persisted.

3
Guard at write time

Collisions update the audit log — they do not create phantom trades.

34-Digit Decimal Engine

Your P&L isn't a rounding error.

Standard floating-point arithmetic accumulates error. The VantageGrid Decimal engine operates at 34-digit precision throughout the full trade lifecycle — entry, size, fees and close-time FX conversion.

AES-256-GCM Privacy Vault

Secrets are encrypted. Lookup is hashed.

Every credential — broker API keys, webhook secrets, 2FA TOTP seeds, OAuth tokens — is encrypted at rest using AES-256-GCM derived from a server-side secret key. Your trade data is never used to train third-party AI models.

  • ✓ Broker keys, webhook URLs and 2FA seeds encrypted at write time
  • ✓ SHA-256 hash used for API key auth — raw value never exposed
  • ✓ GDPR-compliant with documented DPA
