Backtesting Narrow Range Inside Bar Strategy Using Python

When we mention the “Narrow Range Inside Bar,” we are specifically referring to stocks that meet two criteria: they appear in the Narrow Range 7 (NR7) scanner and also exhibit the characteristics of an inside bar pattern.

However, as you have already gone through the earlier chapters of backtesting, You can try out the backtesting method on the scanner of Double Narrow Range 7


In the previous chapters, 

The only thing that needs changing in the code is the dataset because everythin g else exactly the same! So double_ib.csv will become nr7.csv  which was shared in the earlier chapterIt contains all the FNO stocks that has exhibited Triple Inside Bar Pattern since 2015 to today.

					df = pd.read_csv("/root/apps/trident/double_ib.csv")

will become – 

					df = pd.read_csv("/root/apps/trident/nr7.csv")

Now, let’s introduce an intriguing twist. 

Up until now, we’ve been exploring just two exit methods: same-day exit and exit after 5 days. But what if we experiment with a different approach? How about exiting after just 2 days, meaning the trade closes on the next trading day? (In the event that the next day is a holiday, the trade will be exited on the same day.)

Anyways, to do that, We need to change the check_high_breakout_and_save function we designed in our earlier chapter

					to_date = from_date + datetime.timedelta(hours=5)


becomes –

					to_date=from_date+ datetime.timedelta(days=2)


You are welcome to try out different outcomes and play with both the entry and exit conditions!

Comparing the Performance Metrics with Index Inside Bar Intraday Strategy

As the entire codebase will be same, there is no need to re-invent the wheel. Therefore, let’s proceed to examine the three  strategies in parallel to gain a more insightful perspective. Now, it will look nasty in mobile, so it is better You view this in Desktop.

Key Insights from Strategy Analysis

After a thorough analysis of the trading strategies, we’ve unearthed some intriguing findings:

  1. Intraday vs. Positional Exit: The sell strategies exhibit exceptional performance when considering an intraday exit. These strategies seem particularly well-suited for short-term trading.
  2. Buy Strategies’ Strength: On the flip side, the buy strategies shine when opting for a next-day exit or the positional exit after a 5-day holding period. These approaches demonstrate their effectiveness in capturing larger market movements.
  3. Exit Comparison: While the 5-day positional exit strategy boasts superior returns compared to a next-day exit, it’s noteworthy that the next day’s return still amounts to nearly 50% of the 5-day positional strategy’s return. This aspect provides food for thought for traders exploring different exit approaches.
In conclusion, these insights shed light on the nuances of trading strategies and their performance under various exit scenarios. The choice of strategy and exit strategy should align with your trading objectives and risk tolerance.
