This package includes the latest set of SDK files designed to help developers build EAs and Indicators that are able to work directly on the Seconds timeframe chart for MT5.
The Indicators folder contains several example Indicators (Heiken Ashi, HA Smoothed, GMMA, MA, and Vomules) that have been patched to work directly on the seconds TF chart and use the Seconds Chart's OLHC values for calculations.
The Experts folder contains two EA examples that can be used directly on the seconds' chart.
Please see the comments in the EA code for more information.
