In this section, we will apply exponential envelopes to a simple random walk generated using numpy. Here the opening price is also used due to the occurrence of price gaps. Where up_t is the upper extremity, dn_t the lower extremity, and the convergence factor controlling how fast the extremities converges toward the price, with higher length values returning a slower convergence factor. Each extremity calculation with user setting length is given as follows: Let C_t and O_t respectively denote the closing and opening price at time t. These envelopes share some characteristics with the exponential moving average and make use of exponential averaging for their calculations, hence their name.
Estimating Price Extremities Using Exponential Envelopes Exponential envelopes applied to a simple random walkĮxponential envelopes can be described as a trend indicator consisting of one upper and one lower extremity, and as such is similar in practice to indicators such as Bollinger Bands, Keltner Channels, Moving Average Envelopes.etc. If you are not interested in how the indicator is calculated you can directly switch to the “Usage” section below.
Determine the degree of variation of each extremity.Įach of these steps is described in the sub-sections below.Estimate price upper/lower extremities.The Andean oscillator calculation is based on two steps: All the contents in this post are for educational purposes only. Graphics are obtained using Python and the Alpaca Market Data API.ĭisclaimer: The indicator as well as its interpretation showcased in this post does not guarantee profitable results. Codes for the indicator are shared in both python, as well as pinescript for users wishing to use the indicator directly on TradingView. This indicator is based on an online algorithm and can be suitable for high-frequency trading. In this post, a new simple technical indicator (Andean Oscillator) aiming to identify the direction as well as the degree of variations of trends in a security is proposed. Fairly basic indicators such as moving averages, momentum oscillator, and RSI might fail to achieve this task, encouraging traders to pair them with other indicators, ultimately increasing information at the cost of ease of interpretation and ease of interaction. Good technical indicators aim to return a maximum amount of actionable information while remaining easy to interpret and interact with. Technical indicators are part of the many available tools used by traders to aid decision-making in technical analysis. Alpaca does not recommend any specific securities or investment strategies.
