Why Most Traders Struggle, And How SizeMyTrade Fixes It
Most traders obsess over patterns, but it’s the process that determines whether you grow or blow up your account. Your sizing, scaling, and exit decisions shape your true R‑multiple, your equity curve, and your long‑term edge. The problem? Most traders apply these decisions inconsistently.
SizeMyTrade fixes that.
It’s the first tool that turns your entire trade process into a repeatable workflow, from entry to scaling to exits to documentation. You’ll see exactly how each decision affects your stats, your risk, and your performance.
Build your process. Test your approach. Download your plan. Track your evolution. This is how you master the “Process” pillar of PPP (Pattern, Process, Psychology), the part that actually moves your macro stats.

Pattern Performance Tracker
Included with Yearly Plan
The Pattern Performance Tracker Spreadsheet is a comprehensive performance analysis system built for traders who want clear, data‑driven insight into their edge. It lets you log trades, tag them with customizable factor boxes, and filter through any variable you choose—patterns, market conditions, time of day, risk, and more.
All filtered data feeds directly into the Macro Statistics Module, updating key metrics such as win rate, payoff ratio, profit factor, average gain/loss, and R‑multiple performance. This gives you a precise view of what’s working and what isn’t.
Tracking Patterns expands your analysis by allowing variable testing. You can adjust inputs, filter outcomes, and identify the conditions that produce the strongest statistical results for each setup.
Together, these tools provide a structured, flexible environment for tracking, testing, and optimizing your trading performance to turn raw data into actionable insight.
