1. Install Expert Advisor in Metatrader terminal.

   • Go to MT4 (for metatrader 4) or MT5 (for metatrader 5) directory and copy the contents of Include and Experts directories into your Metatrader data folder's Include and Experts directories respectively.

   • Open Metatrader terminal and make sure you have enabled automated trading.

   • You will see NeoTrader expert advisor in Metatrader experts section. Add it to a chart and go to Inputs tab. Set following configurations according to your requirements.

     

     • ServerPort - port of the server to be run. Do not change this for now, because I have hardcoded this port in the browser plugin. I will add a settings page to browser plugin in the future to make this configurable.
     • DefaultRiskPercentage - Risk percentage per trade. This can be overridden using browser plugin.
     • MaximumSplippage - Maximum allowed splippage when executing the trade. This is not applicable to limit trades, so we do not need to worry about this.
     • MagicNumber - A number to identify trades placed by this EA. No need to change.
     • ArrowColor - Forget it!
     • SymbolPostfix - Some brokers add some letters into the end of the symbol name. As you can see in above screenshot, symbol name is EURUSD.a. So .a should be added as SymbolPostfix.
     • CalculateLotSizeToFixedValue - When set to true, expert advisor will calculate lot size to given account balance given under AccountBalanceToCalculateLotSize.
     • AccountBalanceToCalculateLotSize - If CalculateLotSizeToFixedValue is set to true, this value will be used to calculate lot size as account balance.

2. Install Browser extension.

   • Firefox: https://addons.mozilla.org/en-US/firefox/addon/neo-trader/
   • Chrome - https://chrome.google.com/webstore/detail/neo-trader/cjdgehgngjapndihjoddmpiafiagbcpb?utm_source=ext_app_menu

3. Send positions from Tradingview to Metatrader.

   

   • Open a chart in trading view and draw a position using position tool and double-click on it. Position details popup will appear.
   • Open the extension, and it will show the position details.
   • Select desired order execution type. (Market order or Pending order)
   • If execution type is pending, then select pending order type. If set to Auto, EA will determine whether to place to a Limit order or a Stop order according to current price.
   • Then click on Send button. Trade will be placed in the Metatrader platform.

I have used following socket library to build the EA.
