Keltner Channel (MetaTrader indicator) — is a classical technical analysis indicator developed by Chester W. Keltner in 1960. The indicator is somewhat similar to the Bollinger Bands and Envelopes. It uses three plot lines: the middle line is the 10-day simple moving average applied to the typical price ((high + low + close) / 3), the upper and the lower bands are produced by adding and subtracting the moving average of the daily price range (High and Low difference) from the middle line. This way, a volatility-based channel is built. In this version of the indicator you can modify all the parameters of the MA. The indicator is available both for MT4 and MT5 versions of the platform.

QQE MetaTrader indicator — or Quantitative Qualitative Estimation, is based on a rather complex calculation of the smoothed RSI indicators. As a result, you get two lines in a separate indicator window — the fast one and the slow one. There is also an important indicator level (50), which is used in signals. You can enable text, sound, and e-mail alerts for this indicator. This QQE implementation supports multi-timeframe analysis with upper timeframe display. The indicator is available for MT4, MT5

Range Expansion Index (MetaTrader indicator) — is a relative oscillator indicator that measures the pace of the price changes and signals overbought/oversold states if the price demonstrates weakness or strength. It was developed by Tom DeMark and explained in his book The New Science of Technical Analysis. The value of the indicator changes from -100 to +100. The REI is an enhanced oscillator because it tries to remain calm during the range trading and indicates signals only when the significant peaks or bottoms are spotted. You can download this indicator both for MT4 and MT5.

RSIOMA MetaTrader indicator — this indicator takes two moving averages, calculates their RSI (Relative Strength Index) and then also adds a moving average of the calculated RSI. These two lines now can accurately signal the trend changes. They are shown in the separate window where they change from 0 to 100. The auxiliary histogram is shown for a quick-glance view of the current trend. The indicator is available for both MT4 and MT5 versions of the MetaTrader platform.

This script serves as a practical example of how developers can programmatically work with files using MQL5. One of its key objectives is to demonstrate effective project file organization, which is essential for developers working on large-scale systems or aiming to create portable, self-contained projects.
