All the AFL’s posted in this section till now are Trend following. Recently, we experimented on a Mean Reversion Trading System and got surprised with its accuracy and returns. In this post,we would go through this system and its backtest report on NSE Nifty. First, let’s find out what Mean Reversion system actually is.
Mean Reversion Trading System: Definition and Overview
Mean Reversion systems assume that Stock prices oscillate in a Fixed range bounded by an upper and lower price bands. The price always tends to return to a median level in due course of time. In order to trade such system, Buy order is placed at the lower end of range and Sell order is placed at the higher end of range. Any breakout of this range with good volumes may lead to strong trends and trade should be avoided during that time. Strict stoploss is imperative in order to trade Mean Reversion systems. There are many indicators which can be handy for developing Mean Reversion Trading systems. Examples are Bollinger Bands, Donchian channels, RSI, CCI etc.

If we backtest previous periods, I saw some great loss up to 68%, Can you show us how to backtest if possible ?
Thanks.
Hi Harsha,
Can you please let me know in which period you backtested this system and what is the source of your data?
I checked for 2013-14 .. I took the data from the open source. I think it is very similar to the data you provided in your website.. Please check for atleast 3-4 years ..
Your afl is showing error
Corrected. Let me know if it still shows error. Thank you
Dear Sir,
I have an AFL with exploration function, when I explore it to my NSE futures watch-list, I get both current and past signals for every symbol. I would like to know how to get only the current (or the most recent) signals of every symbols in my watch-list. Kindly advise me what AFL command I should apply.
Thank you very much.
Dear sir I want to generate 50% return annually with 20% risk. Will this be an ideal strategy to work for long term. Please let me know. Thanks in advance
Hi Ramendra,
I would not recommend Mean-Reversion strategy for long term. Check out for Trend following strategies instead.
Thanks a lot sir for your prompt reply. Will you please suggest a strategy as per my requirement. That will be very beneficial for the investor who want to trade in future markets.
