Yes, you can definitely do that using the JSON Bridge.
The main difference is that indicator-based trading requires <b>two separate alerts</b> — one for LONG signals and one for SHORT signals.
<h3><b>Step 1</b></h3>
Go to the JSON Bridge and click:
Generate Syntax
Configure your trade settings.
Example:
<li style=”font-weight: 400;” aria-level=”1″>Order Type: Strategy Order
<li style=”font-weight: 400;” aria-level=”1″>Script Type: Future
<li style=”font-weight: 400;” aria-level=”1″>Symbol: NIFTY-N (NFO)
<li style=”font-weight: 400;” aria-level=”1″>Expiry Gap: 0
<li style=”font-weight: 400;” aria-level=”1″>Product: Carry Forward
<li style=”font-weight: 400;” aria-level=”1″>Quantity: 1
<li style=”font-weight: 400;” aria-level=”1″>Transaction Type: Buy / Sell
You can also configure:
<li style=”font-weight: 400;” aria-level=”1″>Exit on Opposite
<li style=”font-weight: 400;” aria-level=”1″>Stop Loss
<li style=”font-weight: 400;” aria-level=”1″>Target
<li style=”font-weight: 400;” aria-level=”1″>Rollover
After configuration, copy the generated JSON syntax.

Step 2: Copy the webhook URL from the JSON Bridge.
Step 3 : Open TradingView and apply your indicator on the chart.
Then create a new alert.

Step 4 :In the <b>Condition</b> dropdown, select your indicator.

Step 5 : For the first alert, select: Crossing Up : This will be your LONG signal alert.

Step 6 : In the Value dropdown below, select the same indicator.

Step 7 : In the Trigger option, select: Once Per Bar Close :
This is generally recommended to avoid false signals.

Step 8 : Give any alert name you want.
In the Message section, paste the JSON syntax generated from the JSON Bridge. Click Apply.

Step 9 : Open the Notifications section.
<li style=”font-weight: 400;” aria-level=”1″>Enable Webhook URL
<li style=”font-weight: 400;” aria-level=”1″>Paste the webhook URL copied from the JSON Bridge
Then click Create

Step 10 : Now create a second alert.
Keep everything exactly the same except:
Crossing Up
should be changed to:
Crossing Down
This will become your SHORT signal alert.
That’s it.

Now:
<li style=”font-weight: 400;” aria-level=”1″>When the indicator generates a LONG signal → Futures BUY order will be placed
<li style=”font-weight: 400;” aria-level=”1″>When the indicator generates a SHORT signal → Futures SELL order will be placed
