This is a very simple idea for Auto-Trading (using Expert Advisor)
My notion would be to follow the major candle. Open a trade in the direction of this candle.
Big Candle is recognized as follows:
The size of candle (from Low to High) is greater than ATR(atr_period) x ATR_Multiplier
So for example, for GBP/USD, H4, suppose ATR(21) has been 30 pips, and we place ATR_Multiplier to 2.5, so we are searching for H4 candles together with range gt; 2.5 * 30 = 75 pips.
So If High-Low of current H4 candle reaches 75 we go extended if candle is up, and we go short if candle is downward.
(There's an Choice to open a trade in the current candle (recommended) OR Await the candle to close)
Take Profit, Stop Loss and Trailing Stop could be of Fixed Pips or Multiple ATR (recommended).
It is better to utilize big TP in order to use Trailing Stop which produces better Rratio.
EA will shut the commerce if an reverse candle appears, and opens a new commerce in the other direction,
Or will wait for SL or Trailing Stop or TP reached and wait for one more trigger.
