hi any one have idea to create this indicator

Directional Relative Volatility Index (DRV)  

Timing is Everything, Three Powerful Methods for Matching Entry Strategy with Risk Posture  by  Robert M Barnes

he Directional Relative Volatility Index (DRV) is a simple but very powerful indicator which represents return (net price change over a given period) divided by risk (average price change magnitude). It is ideal for identifying short-term trading opportunities, especially in choppy markets. The DRV measures how much price energy is translated into a single direction, whether that direction is sideways (indicating no action), up, or down. The DRV allows traders to maximize profits while keeping losses low, or at least low relative to profits. It adapts well to changing market conditions, going to zero in choppy markets, +1 in strong uptrends, and –1 in heavily sinking markets. The DRV, however, can run into problems in choppy markets with low volatility or in very volatile markets exhibiting strong price movement in one direction.
The Volume-Price method updates classical volume analysis to better suit today’s faster paced, real-time environment. It is a fascinating technique that analyzes each countertrend move as it happens to determine if a turning point has occurred or if the trend will continue. Robert shows you how volume drives price and why traders must ascertain that there is a strong volume in the current period to be certain of strong price movement in the following one.

Significant and growing volume reflects a concerted and sustained effort by buyers or sellers to obtain or divest contracts. The trick is to recognize when volume is significant and growing. Robert shows you how to use the relationship between volume and price to make this determination.

Most breakout trading methods follow every countertrend price move until it is confirmed by a secondary signal or the original trend is resumed. Moving average systems smooth out some of the noise from price movements, making trends easier to follow.

The Time-Price method incorporates the best of both these approaches into a system that distinguishes meaningful breakouts from those that are meaningless at the beginning of the countertrend movement. This is accomplished by finding and filtering out special price patterns that do not depend exclusively upon the strength of the price movement. By codifying these mathematical relationships into easily recognizable patterns, Robert provides you with a way to integrate the power of advanced mathematics into your trading system — without having to go back to school!
