Questions about these MT4 indicators

Are these MT4 indicators really free?

Yes. Every file is open-source software released under a redistribution-permitting licence such as MIT, Apache-2.0 or GPL. You get the .mq4 source plus the original licence in each download. There is no paid tier.

Do they work on MT5 as well as MT4?

Some do. Where a tool ships an .mq5 build we include it, but the focus here is MetaTrader 4, so every download contains a genuine .mq4 file. The platform line on each page tells you exactly what is inside.

Will any of these indicators repaint?

We say so on the page when a tool updates on the current bar. Most of these are panels, levels and alerts that do not repaint by nature; for the momentum reads we state the bar behaviour plainly so you are not surprised live.

How do I install one?

Unzip it, drop the .mq4 into MQL4 then Indicators (File then Open Data Folder finds the right place), refresh the Navigator and drag it onto a chart. The step-by-step install guide covers the details and the common mistakes.
