Free Stuff
These are the templates and several of the indicators that I use in my daily trading that are available for free. They just aren't substantial enough to put up for sale in the market. In some cases this might mean that they are not as "polished" as a commercial tool, there may still be some harmless quirks and bugs, but they work well enough (I'm looking at you, Basket Line).
Templates
The basic color scheme that I use, in my favorite templates. Some of these templates include references to other tools (which are included in the download). Some of them are free and are described below; and others available from the MQL5 Market (e.g. Coral Key Levels). You can still use these templates if you don't have all of the tools that are referenced, but it may not look the same as a result.

Coral Basket Line
This is a Break Even (BE) line for traders who are not trying to break even. I realized that a line on the chart based on the basket value (i.e., the position value) doesn't have to only show you a value of zero, and often I want to know what the value will be if price gets somewhere else on the chart. So you can drag this line around on the chart and it will tell you what the position value will be at that price, and the distance. Super handy!

Scaled Moving Average
I know, very exciting, another Moving Average indicator, right? Well, this one lets you set in the inputs what timeframe you want it to be based on, and it will automatically adjust to the current chart's timeframe. For instance, you can see what a D1 MA would look like while you're viewing an M5 chart. Now that's convenient!

Coral HotKeys
Do you prefer the keyboard over the mouse? Have you ever wished that MT4 had keyboard shortcuts to step up/down market watch changing the symbol on your chart; or to step left/right over the chart timeframes? Well, that's what HotKeys does. There's no UI or inputs, so here's an image of Morris showing how easy it is to update your charts with HotKeys.
Coral Target
Useful when position trading and you want to see where the ADR or value targets are, or where the scale-in line is. If you're using CoralMAX or MultiMAX you don't need this, but if you're trading by hand or with another EA that doesn't show you these levels this can be really helpful to see. These lines can't be dragged like with MultiMAX. Does not work correctly with a hedged pair.
