Installing the EA

How to install the Folyze EA in MT5 and paste in the connection key issued on your account screen. You need MT5 running on a Windows PC or VPS (the EA cannot be installed in MT5 on a phone).

Install the EA

WINDOWS (RECOMMENDED)

Install Folyze Manager

It finds MT5 on your PC, installs the EA, and replaces it automatically when a new version ships. Restart MT5 once it is installed.

Download Folyze Manager

The first time you run it, Windows shows "Windows protected your PC". Click "More info", then "Run anyway".

MT5 FOR MAC / BY HAND

Drop in the EA file

In MT5, choose "File → Open Data Folder" and put it in MQL5/Experts , then right-click "Expert Advisors" in the Navigator and choose "Refresh". The EA cannot replace itself, so when a new version ships it tells you in the "Experts" tab. When it does, come back to this page and drop in the new file.

Download Folyze.ex5

Allow WebRequest

In MT5, go to "Tools → Options → Expert Advisors", tick "Allow WebRequest for listed URL", add the URL below and click OK.Without this, the EA cannot send anything to Folyze.

https://api.trade.folyze.io

Attach it to a chart and paste the key

1Drag Folyze from "Navigator → Expert Advisors" in MT5 onto any chart (pick a symbol you can actually trade)
2In the dialog that opens, tick "Allow Algo Trading" on the "Common" tab
3On the "Inputs" tab, paste the connection key from your Folyze account screen into ConnectionKey and click OK
4Turn on "Algo Trading" in the toolbar (the button turns green)

Check that it connected

You are done once "Connected to Folyze" appears in the "Experts" tab in MT5. Your account screen in Folyze switches to "Online", and on the first connection it imports the account's earlier trade history as well.

If it doesn't work

The EA writes the reason into the "Experts" tab in MT5. Find the message you see below.

WebRequest is not allowed (4014): The allowed URL from step 2 is missing. Add https://api.trade.folyze.io and the EA reconnects by itself within 30 seconds.
The connection key is wrong or has expired (HTTP 401): Issue a new connection key on your account screen and paste it into the EA's ConnectionKey. A key is only ever shown when it is issued.
Send failed (GetLastError=…): Check that the machine is online. Once it is, the EA retries automatically.
The EA won't attach, or disappears immediately: The EA cannot run on a chart for a symbol your broker does not offer. Attach it to a chart whose price is currently moving.
A newer EA is available (latest … / yours …): The EA cannot replace itself, so when you see this, download Folyze.ex5 from this page and drop it in again (Folyze Manager does it for you automatically).
Trades made while the PC was off are missing: The EA cannot send anything while it is stopped. The next time you start MT5, everything traded in between is sent at once.
