Momentum Acceleration by DGTItalian physicist Galileo Galilei is usually credited with being the first to measure speed by considering the distance covered and the time it takes. Galileo defined speed as the distance covered during a period of time. In equation form, that is v = Δd / Δt where v is speed, Δd is change in distance, and Δt is change in time. The Greek symbol for delta, a triangle (Δ), means change.
Is the speed getting faster or slower?
Acceleration will be the answer,  acceleration is defined as the rate of change of speed over a set period of time, meaning something is getting faster or slower. Mathematically expressed, acceleration denoted as a is a = Δv / Δt , where Δv is the change in speed and Δt is the change in time.
How to apply in trading 
Lets think about Momentum, Rate of Return, Rate of Change all are calculated in almost same approach with Speed 
Momentum measures change in price over a specified time period, 
Rate of Change measures percent change in price over a specified time period, 
Rate of Return measures the net gain or loss over a specified time period,
And Speed measures change in distance over a specified time period
So we may state that measuring the change in distance is also measuring the change in price over a specified time period  which is length, hence 
speed can be calculated as (source – source )/length and acceleration becomes  (speed – speed )/length
In this study acceleration is used as signal line and result plotted as arrows demonstrating bull or bear direction where direction changes can be considered as trading setups 
Just a little fun, since we deal with speed the short name of the study is named after famous cartoon character Speedy Gonzales

Bollinger bands/Lagging span crossHello my dear ambitious traders 
I'm working hard this week to publish some great indicators this week and open sourced. Hope you'll enjoy, learn and use them. 
This will be my greatest reward but comments showing appreciation are also very welcomed (actually likes too) :) 
For today, I'll share a simple indicator but it's coming along with some insightful knowledge ^^ 
Anyway, I'm not here to ask you to this but to share a very cool indicator I made a few months ago and wanted to share for FREE with the community today 
The indicator is related to this educational post :  What-a-Bollinger-Bands-Lagging-span-cross-can-tell-us/ 
This trading technique was invented by Robbytrade, a famous french trader  twitter.com 
I wanted to have those visual signals on the chart so I coded it. 
The advantage of being a developer is that you can litteraly code what you miss and get your life better in the process. The one that will find a way to code a new form of money will be rich... wait.... that guy is called Satoshi Nakamoto...
That's all for me today my friends 
PS 
Trying to update the Trade Manager shared yesterday with some cool features. More to come in the upcoming days 
Enjoy

Accelerator OscillatorThis indicator was originally developed by Bill M. Williams. Also known as Acceleration/Deceleration Oscillator.
Renko Bar Time by JustUncleLThis indicator in designed to be used with Renko and other price only bars (ie Kagi, LineBreak, Point&Figure) and shows the number of minutes a bar was open before it was confirmed and printed.
 NOTE:  It will only work on currencies and symbols that are in the 24/5 market, it does account for weekend market close time but does not account for any Forex market holiday close times.
 HINTS:  
 
 When the BAR TIME is long and the Renko Bricks have wicks, this is an indication of consolidation.
 When the BAR TIME is short and the Renko Bricks have no wicks, this is an indication of acceleration.  
Williams AC/AO ZonesPaints price bars green when AO+AC are both green, paints bars red when both are red, and paints bars grey when both are different. (IGNORE THE CHART DIDNT MEAN TO PUBLISH IT ON THIS CHART.. OPPS)
