MarketInOut

Stock Screener — Paid

Technical stock screener with relative strength scans, formula filters and backtesting

Custom formula filters paired with a screening strategy backtester

Overview

MarketInOut is a web-based stock screener built for traders who want to filter the market using relative strength, technical patterns, and custom formulas instead of scrolling through tickers by hand. As a stock screener, it covers NASDAQ and NYSE along with more than thirty exchanges worldwide, including the LSE, Xetra, TSX, SGX, and HKSE. This MarketInOut review is aimed at traders and investors who take screening seriously enough to want backtesting behind their rules, not casual browsers. It suits intermediate traders more than total beginners.

The screener itself is the draw. Quick screens cover relative strength, moving average crossovers, chart patterns, channels, and price action, and traders who want more control can write custom formula filters instead of relying on preset scans. A strategy backtester lets you run those screening rules against historical data before trusting them with real money, a step a lot of screeners skip. Watchlists, a portfolio tracker, trade alerts, and an AI screener page round out a toolkit built around global technical screening.

The catches are practical ones. There's no monthly plan, so the smallest commitment is six months, and payments are listed as non-refundable, which raises the stakes on deciding upfront whether this is the right screener. The interface also reads as dated next to newer, slicker screening tools, which matters if you value design as much as function. There's no mobile app and no API access, so this is a desktop-only, manual research tool rather than something built for automation or on-the-go checks.

MarketInOut covers US stocks and global markets, and it's built for swing trading and long-term investing rather than fast intraday setups. Pricing starts at $159 for 6 months, with longer one-year and two-year membership options also available for traders ready to commit further. Skip it if you want a free trial, a monthly plan, or a modern interface; none of those are on offer here. It's worth it for intermediate swing and long-term traders who want serious global screening and backtesting and don't mind a dated interface to get it.
