# Trading Journal vs Spreadsheet

A spreadsheet can work for simple logging, but it becomes fragile when trading data includes pyramids, partial exits, multiple brokers, taxes, charges, and chart evidence.

## Where spreadsheets break down

Spreadsheets usually require manual formulas for realized P&L, taxes, open risk, allocation, monthly reporting, and trade grouping.

Small formula drift or manual row edits can create mismatches between the summary, tooltip, chart, and exported report.

## What Nexus automates

Nexus centralizes broker imports, cross-broker consolidation, trade lifecycle reconstruction, monthly performance, portfolio analytics, tax analytics, drawdown, profit giveback, and chart evidence.

The purpose is not only faster data entry. The purpose is a more reliable review system with less manual reconciliation.

## When a spreadsheet is still enough

A spreadsheet is enough if a trader only needs a simple list of trades and manually reviews every number.

A dedicated trading journal becomes useful when the trader wants repeatable analytics, multiple portfolios, broker sync, tax views, and execution-level accuracy.
