All about Backtests in Tradetron

What is Backtesting

Backtesting is a process by which trading strategies are tested on historical data. Due to the sheer amount of data and computation need, backtesting is very resource-intensive process. Using historical data, we can get an idea whether the trading idea/strategy is performing as expected or not. Backtesting is done as a preliminary step before deploying the strategy in live market. It is to be noted that backtesting and live trading may produce diverse results due to slippage. The time duration required to complete a backtest depends on the complexity of the strategy, the timeframe/candle frequency used and the period/range of backtest.

Backtest Parameters

To conduct any backtest in Tradetron there are certain parameters that users have to input for successful backtesting of strategies.

Backtest Parameters
Backtest Parameters


  • Date Range – Tradetron has historical data available since 1st Jan 2020 to conduct backtests. We have predefined ranges like last 6months, 18months etc or you can also add a custom date range


  • Candle frequency - Users have an option to select their choice of candle frequency from 1min, 5min, 10min, 15min, 30min, 1hr and full day(1D). If you are backtesting a strategy which uses daily timeframe, it would be advisable to select candle frequency as Full day or lower than Full day. Similarly, if you are backtesting a strategy which uses multiple time frame like 15min and 1hr, select candle frequency less than or equal to the lowest time frame in the strategy, in this case it would 15min. The smaller the candle frequency, the more computation is needed which increases the time to complete the backtest.

Note: If your strategy uses time conditions for entry/exit or uses LTP keyword anywhere in the strategy, 1min candle frequency would provide more accurate results.

  • Trade Price – Unlike other backtesting services, Tradetron provides the users with the power to select the trade price of execution. There are two options either Open or Close. Trade price essentially means the price at which the trade is executed. If you are backtesting a strategy that relies on entry after crossovers or any technical indicators, Open Price would be well suited for the purpose. If you are backtesting any strategy that relies on entry on close price basis, select Close in Trade Price


  • Type – Here, you get an option to select the type of strategy you are backtesting,  Intraday or Positional. Kindly select the appropriate option depending on your strategy.
    If you select Positional, it will further provide 3 Options. Select the one that best fits your strategy

1.  None –Select this, if you are trading stocks which do not have an expiry

2.  Weekly- Select this, if you are trading Weekly Options

3. Monthly –Select this, if you are trading monthly Options or futures


Backtest Credit Consumption

Backtests credits usage is calculated based on the backtest period and the no. of underlying in the strategy, if using lists.  For a period of 180 days, backtest credit consumed will be 1. Similarly, if you backtest for 360 days, Backtest credit consumed will be 2 and so on.

#Criteria 1

If underlyings in list >= 5 then max.  5 credits for 6 months period

#Criteria 2

If underlyings in list < 5 then each underlying will consume 1 credit each for 6 month period.

Note - If the list contains more than 20 stocks, the backtest duration is limited to 7 days

Let's understand using the below examples

1. If a user is backtesting a strategy with Index_fut list with 2 underlying Nifty and BankNifty for 6 months, then the count of underlying is 2 in the list. So the Backtest credit required will be 2 for 6 months of data

2. If a user is backtesting a list of 20 stocks for  360 days, since no. of underlying  is 20 which is greater than 5, the max credit it will consume is still  5 for 6 months of data, so in this case, it will only consume 2*5=10 credits for a period of 360 days even though there are 20 stocks in the list

3. If a user is backtesting a simple banknifty straddle for 360 days, backtest credit consumed will be 2


Backtest Status

Once you have posted for backtest, it will reflect the below status sequentially 

  1. In Queue  - This means that the backtest is in queue and will start soon
  2. % Completed - This means that the backtest has started and is in the process 
  3. Generating Report – This means that the Backtest is completed and is currently in the process of generating a detailed report with important metrics
  4. Completed - This simply means that the backtest is complete and you can check your email for reports or can download the same from the backtest page

Note - Once the Backtest is complete, it will move to the Completed section

Interpreting Backtest Report

As soon as the backtest is complete, a comprehensive detailed backtest report is sent to the user’s email address. This report consists of key performance metrics for the strategy. You can also download the Stats pdf and positions CSV from the backtest page too. It makes it very convenient for the user to do their own analysis based on the trades taken by the backtest engine.

Backtest report consists of the below stats

PNL Curve – A PNL curve is a graphical representation of the change in the value of a Profit/loss over a period of time

Capital Required - The total starting capital for the strategy

Total PNL - The total profit/loss generated during the entire backtest period

Drawdown - Drawdown expressed in % terms refers to the degree to which the PNL curve drops from the peak (Highest point) to a trough (Lowest point)

Standard Deviation - Standard deviation is the statistical measure of volatility. It is also expressed in % terms. The lower the, the more reliable the strategy.

Sharpe Ratio - Sharpe ratio is a measure for calculating risk-adjusted return. Strategies with higher market excess returns and lower volatility will show higher Sharpe Ratios. So naturally, higher is better. For Annualized Sharpe Ratio, the Risk-free rate is considered as 0

Total Trading Days - Total no. of trading sessions in the selected backtest period

Win Days - This parameter tells you the no. of profitable days 

Loss Days - This parameter tells you the no. of loss days

Win Rate – Simply put, this parameter tells the trading system’s win ratio. The bigger, the better. It is calculated using the formula - < Total profit days / Total trading sessions in Backtest period>

Avg Monthly Profit – Average profit generated per month 

Avg Monthly ROI – Average ROI generated per month, Capital is considered as the base of all returns. It is calculated using the formula - < Total PNL/ (Total trading days * 21) >

Total ROI – Total ROI generated for the duration of the backtest. 

Max Profit in a Day — Maximum Profit generated in a trading day

Max Loss in a Day  – Maximum Loss generated in a trading day 

Avg PL Daily – Total PNL/total trading days in the selected backtest period

Avg Profit on Profit Days – Average Profit generated on Profitable days

Avg Loss on Loss Days – Average Loss generated on Loss days

Avg no. of trades (Buy + Sell) per day – Average no. of  trades in a day(Only sessions on which strategy took trades are considered)
