Why do trend lines (e.g., D1 lines) sometimes not align correctly on lower timeframes (e.g., M15 or M5) in MetaTrader?

This common issue of trend lines not aligning correctly on lower timeframes is typically caused by a bug or inconsistency in how MetaTrader itself loads historical data, and it is not related to the ForecastFollow software.

Explanation of the Problem:

MetaTrader may not fully load all historical candle data for a specific period when loading chart history. This results in missing or incomplete candles in your chart's data. Since software like ForecastFollow relies on complete and continuous historical data for accurate line drawing and forecasting, the absence or incompleteness of these candles prevents the correct rendering of trend line angles.

Example:

As you observe, approximately one year and three months of 5-minute candle data are missing from this chart's history. Consequently, ForecastFollow cannot accurately draw the angles of the lines because the necessary data is incomplete.

Solution: Ensuring Complete Candle History Load in MetaTrader

To effectively resolve this issue and ensure the precise display of trend lines, it is crucial to ensure that all necessary historical candle data is fully loaded and present in your MetaTrader's history and chart. Follow these steps:

1. Re-download History Data:

• • In your MetaTrader software, press F2 to open the History Center.
  • In this window, navigate to the specific currency pair and timeframe, and then re-download the historical data. This helps fill in any potential gaps in the data.
  • 

2. Adjust Maximum Bars in Chart Settings:

• • To open the Options window, press CTRL + O.
  • Go to the Charts tab.
  • In this section, find the settings for "Max bars in history" and "Max bars in chart." Set both of these values to their maximum possible limit.
  • The maximum number MetaTrader accepts is typically a very large number (e.g., 999999999 or the highest value allowed by your MetaTrader version).
  • 

Important Notes:

• Performance Impact: Please be aware that increasing the number of bars in history and on your chart will require more memory and processing power from your MetaTrader software. This may cause MetaTrader to load charts slower, as it needs to process and display a significantly larger amount of historical data.
• Data Integrity: These steps are paramount for the accurate and reliable display of all indicators and lines, especially those provided by ForecastFollow, as their precision directly relies on a complete and consistent historical data feed from MetaTrader.

By diligently following these steps, you will ensure your MetaTrader charts have the complete historical data required for ForecastFollow to display trend lines and other analytical elements with optimal accuracy, significantly enhancing your trading analysis.
