How much data is available for Deep Backtesting? ›

Please note that Deep Backtesting is only available to Premium users and professional traders, and the maximum number of available bars for backtesting is 2 million.

Aim for at least 200 trades in your backtest, but 500-600 offers even greater reliability for informed decision-making. Beware of "Data Fatigue": Excessively long backtests can mislead you by including drastically different market regimes.

Evaluating Backtesting Results

When it comes to evaluating the results of your backtest, we can focus on a few important performance and trading metrics. However, it is important to remember that a sample size of at least 30 (ideally 50) trades is necessary to get statistically significant results.

While Professional plans offer more historical intraday data: Expert plans have access to 25000 bars, Elite plans have access to 30000 bars, and Ultimate plans can have the maximum number of historical intraday bars, which is 40000. The current limits for each plan can be found on the pricing page in the Data section.

Please note that the maximum length of historical data per calculation is 2 million bars. If the period used for a backtest covers more than 2 million bars, the strategy will execute on the most recent 2 million bars within the selected period.

To be 70% confident with a projection that has a 5% margin of error we need 101 trades in our sample. To be 70% confident in your statistical result, you need at least 107 trades in your test sample; to be 99% confidence you need 666 trades.

Many statisticians concur that a sample size of 100 is the minimum you need for meaningful results. If your population is smaller than that, you should aim to survey all of the members. The same source states that the maximum number of respondents should be 10% of your population, but it should not exceed 1000.

It is calculated as the ratio between annual returns and the Maximum Drawdown the strategy exhibits (Return/Max DD) during the backtest period. For example, if a backtest report for a strategy illustrates a return of Rs 1,00,000 and a maximum drawdown of Rs 15,000, the R/MDD or Calmar Ratio is 6.66.

As a general rule, sample sizes of 200 to 300 respondents provide an acceptable margin of error and fall before the point of diminishing returns.

The current limits for the equity index futures are + and - 7%, 13%, and 20% from the previous day's settlement price. If price reaches these levels trading is either paused briefly or for the remainder of the day.

I Personally do back test for 6 months to 1 year. some strategies will not be favourable when you go beyond 1 year+. Atleast 6 months is mandate for a good strategy, If a strategy gets max number of profitable trades in last 6 months thats enough.

In summary, TradingView provides powerful tools for both manual and automated backtesting. However, remember that backtesting is just one part of strategy development. Past performance doesn't guarantee future results, so always trade with caution and proper risk management.

A well-conducted backtest that yields positive results assures traders that the strategy is fundamentally sound and is likely to yield profits when implemented in reality. In contrast, a well-conducted backtest that yields suboptimal results will prompt traders to alter or reject the strategy.

In other words, there is a very high chance that the strategy is a profitable trading strategy. It takes around 1 hour to back test a strategy 100 times.
