Average Bid/Ask Spread

The "AvgBidAskSpread" is a parameterless function that calculates the average ask price for the current bar minus the average bid price for that same bar.

The indicator uses the newly introduced CSharp-based "cFunctions.GetBidAskData" function to capture last bid/ask updates and performing the necessary calculations.

You can plot this indicator to a chart simply by adding the following formula:
a = AvgBidAskSpread();
plot(a, "", colorGreen);

Note that in order for this function to work, you must apply it to a chart that is connected to a data feed. The data feed must also support bid/ask updates (most of them does).
You can use this formula is any intraday period but it is important to note that only the last 1000 updates (including last, bid and ask) are used in the calculation. This is because only the last 1000 updates are stored in memory.
