Ea should use the RSI indicator or other (Stochastic oscillator or EMA or MACD) to enter the trade. To enter BUY, the RSI must cross the bottom up the value specified in the EA parameters (for the sales, on the contrary, cross from top to bottom).

In case of a successful entry, the transaction closes either according to Take Profit, or Trailing Stop is used.

If the market goes in opposite direction, the order grid opens at a specified distance from the average price of the grid. Also, newly opened orders can be filtered using Bollinger Bands indicators (for example, Sell opens only if the price has closed above the upper Bollinger Bands limit) and Moving Average (for example, Buy opens only if the price has closed below Moving Average).
