would anybody modifiy Price-Volume Rank?

would anybody modifiy Price-Volume Rank? For EOD it is giving good prediction before price breakup. But i`m missing buy/sell signal visually.

Piash,

AFL is simple. You should start with some simple AFLs.

Here is the code for you.

// market. Make another indicator using a double-smoothing to use a less
// volatile graph. Thanks to Donald Dalley for the description

Buy = Cross(2.5, PVR_MA1);
Sell = Cross(PVR_MA1, 2.5);
