While trading in Options pine script can be used on charts of Nifty Cash/Future for applying your NSE options Algo Strategy in TradingView. Note this strategy works good with even free version of TradingView.

Strategy Premise

The Relative Strength Index (RSI) is a momentum oscillator that measures the speed and change of price movements. The RSI oscillates between zero and 100. Increasing RSI shows increasing bullish momentum. Decreasing RSI shows increasing bearish momentum. We take RSI upper bound as 80 to indicate bullish momentum and RSI lower bound as 20 to indicate bearish momentum.

We use the above premise to create options buy-only strategy which trades in ATM strikes by default. This strategy requires very less margin (Rs. 15000 should be sufficient).

NSE Options Algo Strategy Logic

Long Entry: When RSI goes above 80, send LE in auto-calculated option strike Call. When RSI goes below 20, send LE in auto-calculated option strike Put.
Long Exit: When we hit Stop loss or Target. In case SL/TGT do not hit and reverse RSI goes above 80 send Long Exit in auto-calculated option. Put as per last trade; RSI goes below 20, send LX in auto-calculated option call as per last trade.

For Long and Short entry the order is fired in option buying side with auto strike price selection.

APIBridge Settings – New Users

This is an advanced strategy. In conclusion you are first requested to complete TradingView Jump Start Setup. Make sure you use the extension v4.1 for this strategy.

We advised to add all the option symbols in Apibridge before setting alerts, to avoid order rejections. In addition make sure you use same expiry, and strategy tag as given in trading view. Since we send quantity in alerts there would be no need to specify quantity in APIBridge Symbol Settings.

APIBridge Settings – Advanced Users

You can completely bypass the symbol settings using config file edit as given on the bottom of this page. However the pine script code uses optimal alerts which do not require any symbol settings.

Sample Trades

See sample trades below with RSI on 1-minute chart.

The first entry for day is taken at 9:35:02 and second at 9:45:01. As RSI swings to other extreme as a result previous option position was closed and new position was created.

Note : All the trades show price as 0, because market orders are used.

In APIBridge paper trading mode, you will not be able to see correct PnL because underlying instrument is different from trading instrument. However, in live trading you will see actual option prices in trades.
