Building the Pin Bar EA

Pin Bars are one of the mainstays of candlestick reversal patterns. What if we could code them into a robot and trade them automatically whenever they appear?

This article will teach you how.

We will first need to define a ‘Pin Bar’ so the computer can read it.

Bullish Pin Bar

1. Bar Close > Bar Open
2. Bar Body < 25% of Bar range (high – low of bar)
3. Bar Open > (Bar low + 75% of the total bar range)

Bullish Pin Bar (simple explanation)

1. Bar close needs to be greater than Bar open (for bullish pin bar)
2. Bar body needs to be less than 25% of Bar range (A pin bar has small bodies)
3. Bar open needs to be in the top 25% of the of the Bar range.

Let’s code it!

Step 1 – Code outline

1. Check for new bar
2. If there is a new bar, check total number of orders
3. If there are no orders, check for buy and sell signals
4. Place orders

Step 2 – Defining the entry signals

Remember this from earlier?

1. Bar close needs to be greater than Bar open (for bullish pin bar)
2. Bar body needs to be less than 25% of Bar range (A pin bar has small bodies)
3. Bar open needs to be in the top 25% of the of the Bar range.

Here is the explanation of the entry signal:

Step 3 (last step): Placing a trade

1. Once the above buy condition is met, the EA will place a Buy order
2. The order is placed using the PlaceOrder function, which you will have access to when you download the code below
