Uploading Chart Images to Twitter from MQL5 Without External DLLs

Summary

This article explains how to extend a native MQL5 Twitter client to publish tweets with photos. It describes OAuth-authorized multipart/form-data uploads, constructing the request body with raw image bytes, retrieving each upload’s media identifier, and joining identifiers into the parameter used when posting a tweet. The example script captures charts and attaches up to four images, while the class also provides credential verification and basic response parsing.

The material is an implementation guide rather than a trading method or performance study. It recommends raw binary uploads over Base64 to reduce request size and notes that uploaded media identifiers are temporary. The author presents the class as a simple starting point, warns that its JSON extraction is rudimentary, and identifies API constraints and image size/type restrictions as relevant. It does not evaluate whether chart sharing improves trading decisions or provide evidence about strategy outcomes.

Key ideas

• Photo uploads use an OAuth-authorized multipart HTTP POST request.
• Raw binary image data is smaller than Base64-encoded data for the upload.
• Each uploaded image returns a temporary media identifier that can be attached to a tweet.
• The example gathers chart screenshots and combines identifiers to include multiple photos in one post.
• The client is a basic implementation, and its string-based JSON parsing is not fully compatible.
