MQL5 Source Codes of Libraries for MetaTrader 5

Automates MQL5 buffer and plot index management. Eliminates manual counting, simplifies Z-order layering, and handles complex plot types (Candles, Color Lines) with a single line of code.

Securing data transfer between client and Server could be a big challenge for you as MQL5 programmer. You may have experience in using built in MQL5 encryption systems like AES.AES can securely encrypt your data but on the other hand is not secure when it comes to sending the AES key through insecure channels. You can only rely on asymmetric encryption systems Like RSA in such cases. you keep the private key at your server side and only share the public key with your clients. Even more you can use hybrid RSA_AES approach to archive more performance

Multisymbol OnTick.

Structure of input parameters

Library for trading session control. At startup it counts the time of trading sessions for all 7 days of the week (on Sat and Sun there can be cryptocurrency trading), up to 10 sessions per day. Then in OnTick() you can do checks, and if a tick came in outside the trading session, you can exit further processing of it.

Compression of tick data for storage in a compact form up to 3.5 times more compact than .tcs MQ files. And for fast work with them, because reading 3 bytes takes less time than reading 60 bytes of MqlTick structure.

A JSON library that supports MQL4/MQL5

CDateTime milliseconds extension + datetime supervisory variable extension

Records ticks in real ticks mode and reads them in maths mode calling your strategy with each tick.
