How to set sound alerts on your Android smart device for premarket or postmarket trading on TradingView

1. On the price chart, select a timeframe that is smaller than 1 day, such as 1 hour or 15 minutes. The price chart should now show 2 new vertical coloured bands that represent pre-market and post-market periods.

2. Add an alert, then:

> Settings > Symbols: ([ticker], Extended trading hours)

> Notifications > Send plain text to alternative email 

2.1 Note on email address to use:

User profile > Profile Settings > Private Details > Alternative email for alerts (edit this)

- insert a hotmail address (the hotmail app can detect incoming emails and trigger sound alerts on your smart device)

- don't use gmail address (the gmail app cant seem to achieve the same above)

3. If using gmail website:

Gear > See all settings > "Filters and Blocked Addresses" tab > Create a new filter > From(noreply@tradingview.com) , Subject(Alert)

4. Label it, mark it as high priority/important

5. Select sound notification

6. Test

Setup hotmail (outlook.live.com/mail)

- Settings > General > Notifications > 

-- Notifications in outlook (on)

-- Notify me about Mail (on)

-- Play sound (on)

Setup hotmail app to trigger ringtone

- Outlook app > Settings > Notifications > 

-- Allow notifications (on)

-- From (All email) (Note: Outlook app doesn't have the function to send notification when email lands in a specific subfolder, so you'll have to make do with "all emails")

-- New email sound (SELECT YOUR MP3 HERE eg 20210307_Aiden.mp3 , RM_alarm.mp3)

Setup gmail app to trigger ringtone

Create your label: Gmail website > select correct account (xxx@gmail.com) > (see LHS panel) Create new label > name it "TradingView Alerts"

Define your target emails and assign them the label:  Gmail website > Settings > Filters and Blocked Addresses > Create a new filter > From (noreply@tradingview.com) & Subject(Alert) > Create Filter > ApplyTheLabel(TradingView Alerts) & NeverSendToSpam > CreateFilter

Receive any incoming emails and label as necessary: Gmail app > Settings > Select correct google account (xxx@gmail.com) > InboxNotifications (Notify Once) > SyncMessages(Last30days) & LabelNotifications(Yes) & NotifyForEveryMessage(No)

Let any Labelled Email trigger an Alert: Gmail app > Settings > Select correct google account (xxx@gmail.com) > ManageLabel > TradingView Alerts (Last30days) > Sync Messages (The previous 30days of messages will download when connected) > LabelNotifications(Tick YES) > NotifyForEveryMessage(play sound when each new message arrives)(Tick YES) 

Select Alert Sound: Gmail app > Settings > Select correct google account (xxx@gmail.com) > NotificationSounds > GoToDeviceSettings > AllowNotification(On) & GentleNotificaitons(off) & Banners(Off) & LockScreennotifications(Show) & AllowInterruptions(No) & NotificationSound > MusicOnDevice > Search for your file (___.mp3)

Let Gmail app keep receiving emails in background: AndroidDevice > Settings > Apps > App launch > Gmail(off) (flick to "on" then finally leave it as "off", and you'll see the subsequent menu) > Autolaunch(on) & SecondaryLaunch(on) & RunInBackground(ON)

- Test by sending TV alert to your email

Warnings/Disclaimers

We suspect the gmail hack works only for accounts identified as "https://mail.google.com/mail/u/1/". Alerts don't seem to trigger for accounts ending with ".../mail/u/0" or ".../mail/u/2" etc.
