Volume spikesSimple indicator which shows volume spikes.
By default spike is defined as such when volume is 2 times higher than average volume for last 10 volume bars (this can be changed in settings)
Also instead of using average volume (SMA is used in this case) you can use WMA or EMA by changing settings

Spike Day's definition taken from Jack D Schwager's Book: A Complete Guide to the Futures Market: Technical Analysis, Trading Systems, Fundamental Analysis, Options, Spreads, and Trading Principles
A spike is:
A wide difference between the spike high and the highs of the preceding and succeeding days.
A close near the low of the day's range.
A substantial price advance preceding the spike's formation.
The more extreme each of these conditions, the greater the likelihood that a spike high will prove to be an important relative high or even a major top.
(inverse is true for lows, basically)

Volume SpikeThis script identifies volume spikes as a percentage change of the current bar's volume compared to the previous 3 bars' average volume.
