EMA crossover trend follow

Also called: Trend follow, EMA crossover, EMA 20 and EMA 50 cross, low risk chart strategy.

Trend follow is a fixed chart rule with a low risk level. It watches 2 lines, EMA 20 and EMA 50. EMA 20 moves faster than EMA 50. When EMA 20 crosses above EMA 50, the rule plans a Buy. When it crosses below, the rule plans a Sell. Each trade gets 3 prices before it starts: the entry, the stop and the target. The stop is where the trade gives up. The target is where it takes the gain.

Formula

Step 1: wait until more than 50 candles have closed, so both lines are ready. Step 2: Buy when, on a closed candle, is above EMA 50 and on the candle before it was not. Sell is the mirror. Step 3: entry = the next candle's open. Step 4: stop = entry - 2 x . Step 5: R = entry - stop. Target = entry + 2R. Step 6: the trade ends at the target, the stop or the day's last close. If 1 candle reaches both, the stop counts. Only 1 trade runs at a time.

How it is read

Here is an example. ATR (average true range) is the usual size of 1 recent candle, from high to low. Say ATR is 25 points and the next candle opens at 25,300. The stop is 25,300 - 50 = 25,250. R is the gap between the entry and the stop, so R is 50 points. It is what 1 trade loses when the stop is hit. The target is 25,300 + 100 = 25,400. That is 2R past the entry. Here is how a trader can win with this rule. Each win is 2R and each loss is 1R. So you can be right on only 4 trades in 10 and still come out ahead. Take 4 trades. 2 hit the stop for -2R and 2 hit the target for +4R. The total is +2R, which is 100 points here. A win is more likely when you take the cross on a closed candle, trade in the direction of the bigger move, and keep the stop where the rule put it. When a stop is hit, the stop did its job. It kept that loss to 1R, as planned. Low risk level here means a wide stop. Small wiggles rarely reach it, so it is hit less often. To try it, open Paper Trading and turn on EMA 20 and EMA 50 in Indicators. Write down the 3 prices before you place an order for 1 .

What it does not tell you

The rule struggles in a sideways market. The lines cross back and forth, and each cross can end at the stop. Crosses inside flat, tangled lines are the ones that most often end at the stop. The rule is also late, because part of the move is over by the time the lines cross. If the day ends first, the trade closes at the last candle. A gap past the stop can make a loss bigger than 1R. On our practice markets this rule wins some trades and loses some.
