The RobotFX Traders Dynamic Index Expert Advisor is built specifically for traders who love the TDI indicator. The Traders Dynamic Index combines RSI, Moving Averages, and volatility bands into one powerful tool that shows trend direction, momentum, and market volatility at a glance. This TDI EA for MT4 automates the entire process, allowing you to trade the trend with confidence while removing emotional decision-making.
In the chart above you can see one of the common ways to read the TDI indicator: the yellow line shows the main trend, while crosses between the green and red lines often signal potential entries.
|
| In this example, the EA trades with the trend (green candles = buy) and enters trades when the TDI green moving average rises above the TDI red moving average. The trade exits when the Stochastic leaves its overbought zone, set at 95 for this example. |
|
| The TDI EA determines the trend using the MA Trend and uses Stochastic as a confirmation filter. Entries are triggered by TDI red/green moving average crosses. Several TDI signals are ignored due to confirmation criteria. Trades are opened and closed based on combined TDI and Stochastic conditions. |
|
| This trade follows the trend (red candles = price below MA). Entry occurs when TDI green MA crosses the upper volatility band down; the same signal is used for exits. Swing zone confirmation is applied to enhance trade accuracy. |
|
| Here, the TDI EA trades without trend detection or confirmation. Entries and exits are based solely on TDI green line crossing the volatility bands. White vertical lines mark entries; black lines mark exits. This strategy aims to capture large market moves efficiently. |
|
| The TDI EA follows the MA Trend for trading (sell below MA, buy above MA) and opens trades based on the TDI green moving average slope. Maximum three trades are allowed; exits are triggered when TDI green and red lines cross. Profit/loss from individual trades is managed to ensure overall basket profitability. |
Since the TDI expert advisor uses the TDI indicator, all the indicator's settings can be found in the EA's settings.
