Connect TradingView signals to MT4 using webhooks

Hi second time (I deleted previous order by mistake),

I would like to connect my TradingView signals to MT4 using webhooks. As of now, using my own Telegram channel seems to be the easiest and safest option. 

Now Im using this solution https://www.tradingviewtomt4.com/

Here is the overall flow: 

1. Alert setup in TradingView (from strategy script)
2. TradingView generates alert when condition is triggered (currency + order type + risk management or lot size from alert comment field).
3. TradingView sends alert using Webhook URL field to send the signal to Telegram - I want to use this default syntax from tradingview   
4. Telegram reads signal data and forwards signal detail to MT4 EA 
5. MT4 opens order. EA can works with default lot size (i can set in tradingview messsage) or risk management calculation based on this https://www.tradingviewtomt4.com/blog/why-risk-manegement - Im using this just now, but the EA is not 100% reliable and the syntax is limited.
6. Im using multiple accounts on one VPS (3-4 MT4 apps on one desktop) - I need the account identification and send signals to the specific account (will be in the Tradingview message)
7. I need Central % equity stop (close all trades and stop autotrading/bot) + Notification when robot is stopped - I can set SL for all trades on acount for example on 50% of my account equity (should be calculated from last balance), then close all trades and stop automatic trading on metatrader and send notification to MT4 mobile app.

I want to use this placeholder to build my alert's notification message. They will be replaced by their corresponding value when the alert triggers. ( )

• {{ticker}} - returns SYMBOL (EURUSD, BTCUSD, EURGBP, …)
• {{strategy.market_position}} — returns the current position of the strategy in string form: “long”, “flat”, or “short”.
• {{strategy.order.alert_message}} - returns specific message from EA (account and risk management in my case)

Message from tradingview looks like this:

Open Orders:

long_SYMBOL_account_SLinPoints_Risk%
short_SYMBOL_account_SLinPoints_Risk%

example:

long_EURUSD_111222333_150_0.05 = opens a long order on EURUSD  on account 111222333 with an SL 150 points away with 5% risk if SL triggers
short_EURGBP_222333444_300_0.03 = opens a short order on EURGBP  on account 222333444 with an SL 300 points away with 3% risk if SL triggers
long_EURJPY_222444666_300_0.00= opens a short order on EURJPY on account 222444666 with an SL 300 points away and the default lot size (I can set in EA)

Close Orders:

flat_SYMBOL_SLinPoints_Risk%_account

example:

flat_EURUSD_111222333_150_0.05 = close all orders on EURUSD on account 111222333 (with „flat“ order everything else in the text after account number has to be ignored)

The signals form tradingview can come in the same time - it is necessary to follow the sequence of signals

I look forward to answering your questions if any. Developer with proven experience will be preferred. 

It is not a problem to increase the budget if its necessary.

Thank you :-)
