Detect and Display Potential Splits on a Chart

Here is a nice function that displays potential stock splits on a chart.
By simply adding the "DetectSplits" function to your chart, you will be able to quickly see whether the stock data has potential non-adjusted splits or not.
The function can detect many types of splits and reverse splits, including 3:1, 2:1, 1:2, 1:3...

"DetectSplits" function has only one parameter that is called "sensitivity". The higher the sensitivity value the more splits this trading indicator will be able to detect (and potentially more false positive).

Note that a "Split" function (Symbol -> Split) already exists in QuantShare. It allows you to analyze a symbol to automatically detect potential splits. It also allows you to adjust data for these splits (or any manually entered split ratio).

Besides displaying potential splits on a chart, the function also returns "1" (true) on bars where the potential splits may have occurred.

This is very useful, for example to quickly detect the bar where a split may have occurred:

a = DetectSplits(10);
PlotArrow(a == 1, "Split", AboveHigh, colorRed); // This will plot an arrow on potential split bars

Or you can use this to prevent a trading system from entering a new trade on a potential split bar/date:

[Your trading system rules]
a = DetectSplits(10);
buy = buy and !a;
