345 Strategies

Tools for traders and investors smart enough to keep it simple.

The idea

Trading is hard enough.

Every trader knows the real work happens off the screen. The journaling, the review, the learning to sit on your hands. Nobody can do that part for you.

The screen is another story. Charts pile on indicators, indicators pile on opinions, and somewhere underneath is the only thing that matters: what price is actually doing.

That's what we build for. We believe in simple systems, the kind that keep you objective when money is on the line. Tools that take in complex information and show you only what's relevant. Markups you'd otherwise draw by hand, drawn for you, the same way every time.

Fewer variables. Fewer judgment calls that don't need making. More attention left for the part only you can do.

The tools

Modern applications for charting platforms and agentic trading.

Make trading as simple as three, four, five!

These are price action tools, not black box algorithms. Each is built on a mix of proprietary methods, heavily influenced by TheStrat, the methodology developed by Rob Smith.
