✅ Read everything about SignalX here.

Once you've gone through the Notion doc above, come back here for instructions to setup SignalX!

Setup Prerequisites:

1. Sign up on DigitalOcean using this link. You'd receive $100 in new signup credits valid for 2 months. Running this app costs $10/month. So you'd be able to run it FREE for first 2 months.

2. Goto https://kite.trade and sign up for Kite Connect. Create an app and pay Zerodha the ₹2000/month fee.

   • Ignore the Redirect URL and Postback URL fields for now.
   • Copy API Key and API Secret fields and keep them handy somewhere.

3. Goto https://redislabs.com/try-free/ and sign up for a "Cloud" redis account.

   • Activate your database and name it signalx
   • Copy the Endpoint and User Password fields to construct the following Redis URL - redis://:{User Password}@{Endpoint}. Keep this handy. (remove the curly braces)

Update - Redislabs free tier drops connections very often. Recommend upgrading to a paid tier for a seamless trading experience.

1-click Installation

MOCK_ORDERS

Set it to true if you'd simulate orders but not actually place them on Zerodha. Comes in handy if you're looking to develop this application locally. Ignore it otherwise.

NEXT_PUBLIC_DEFAULT_LOTS

Default lots that you trade on a regular basis. This is only the default initial value in the form and is changeable before taking the trade.

for e.g. If you regularly trade 150 quantity of Nifty Options, you'd enter 2 lots here.

NEXT_PUBLIC_DEFAULT_SKEW_PERCENT

Default skew that you're okay with when selling straddles. Anywhere between 5-15 is a good value. The value here only serves as a default and can be changed before setting up daily trades.

NEXT_PUBLIC_DEFAULT_SQUARE_OFF_TIME

Default square off time of the strategy. The value here only serves as a default and can be changed per strategy during the strategy setup when taking daily trades. Format is 24 hours hh:mm. i.e. enter 15:20 as value if you mean 3.20pm.

NEXT_PUBLIC_APP_URL

Enter ${APP_URL} here or leave this value as it is if you're doing a fresh setup as the value will be correctly prefilled for you.

SIGNALX_API_KEY

Upgrade to SignalX Premium to receive your API key. SignalX Premium gives you access to technical indicators required to trade certain strategies.

DATABASE_HOST_URL

DATABASE_USER_KEY

DATABASE_API_KEY

Follow the upgrade guide here to get values for all these 3 variables.

NEXT_PUBLIC_DEFAULT_SLM_PERCENT

Default percent of SLM BUY orders to be placed after initial order goes through. The value here only serves as a default and can be changed before setting up daily trades.

NEXT_PUBLIC_GIT_HASH

Leave the value in this field as it-is. This'll inform if there's an app update available in the app UI. If there's an update available, you can hit the "Deploy" button in your DigitalOcean app to install the new build for yourself.

Next Steps

• DigitalOcean Step 2: After entering all environment variables in setup Step 1, proceed to the next step and select Bangalore as region.
• DigitalOcean Step 3: Select $5/mo container size from the Basic size dropdown. Ensure you see $5 as the Monthy App Cost.
• Click on Launch Basic App.
• Give it 5mins, let the application get build.
• Once successfully built, Goto Settings of this app, and copy the URL where DigitalOcean hosted this application for you.
• Go back to the kite app, and now enter Redirect URL as follows: {url_from_digitalocean}/api/redirect_url_kite. It should look something like this https://qwe-qwerty-gex5y.ondigitalocean.app/api/redirect_url_kite (only an example - yours will differ). Press Save!

Using the application

• Bookmark the URL, or save it to your homescreen. You'd need it every trading day!
• Zerodha automatically expires the authentication token required to access the APIs at around 7.35am. You're required to login to this app every day after 7.45am to generate a new access token.
• Once logged in, you'd need to setup your trades for the day. This needs to be done everyday!. Trades setup after market hours will fail the next day as the API access token would have expired.

Data and Security

• All access tokens are saved via a first-party cookie in your browser and are encrypted via the SECRET_COOKIE_PASSWORD environment variable. Whatever you do, DO NOT share this with anyone!
• Redis is used for scheduling the tasks or running them on spot. DO NOT share your redis URL with anyone as it contains your Zerodha profile details alongwith API access tokens.
