Bollinger Bands is an effective tool as everyone knows already so I will not introduce again. We will go into the main topic too, which is discussing the strategy of using two Bollinger Bands for trading.

All we need to do is add two Bollinger Bands indicator lines to the price chart.
+ Bollinger Bands first we leave the default parameter (20,2,0), parameter deviations to be 2.
+ The second Bollinger Bands to the parameter (20,1,0), parameter deviations to be 1.

In this article, I call for short Bollinger Bands (20,2,0) is BB2, and Bollinger Bands (20,1,0) is BB1 for fast.

After adding two BB lines, the graph should look like this:


The two outer boundaries are the boundary of BB2, while the two inner borders are of BB1. As for the middle road, in the system I'm going to show below, we won't use it. Maybe we only use it to maximize profits, but it does not act as an entry point or exit. So just pay attention to the upper and lower boundaries.

WHEN BUY?

To enter a buy order, we have to wait for the candle to close above the upper boundary of BB1. Then you check to see if the previous two candles closed below the upper boundary of BB1. If these two conditions are met, BUY.

I will give you an example of USDJPY pair on D1:


As shown in the image above, the candlestick 3 closed above the BB1, and tree 2 and 1 closed just below the BB1. So that means we can enter a BUY order at the close price of tree 3.

The stop loss will be placed at the bottom of kilometer 3 a few pips. Takeprofit is twice as high as Stoploss. When the price runs half of the take-profit, you move the stop loss to the entry point to protect the results.

For example, if you enter an order, as shown above, stop loss = 60, take-profit = 120. The price can run 60 pips, then we move the stop loss to the original entry point.

Here is another example. We also enter the order at tree 3, notice that trees 2 and 1 must close below BB1.

One more example:

And one more example:


Occasionally, PK 3 not only broke the upper boundary of BB1 but also broke the upper boundary of BB2. This time signals that the trend is very strong:



Note: if tree 3 is too long, we should not place it at the bottom of tree 3 anymore, but just place it according to your tolerance for risk.

WHEN SELL?

Similar to the BUY command rule, we have to wait until the 3rd kilometer closes below the BB1, the 2 and 1 kilometer closes above the BB1, then place the SELL command at the closing price of kilometers. 3.

Stoploss and take-profit are similar.


HOW DO YOU EAT THICK, DEEP, AND WELL?

This method is very good at catching a trend. Therefore, you have to take advantage of the current trend to eat thick, deep and bold.

Here is the method:
+ When there is a good entry point, you enter two commands with 1 stop loss (instead of every 1 command 1 lot, now enter 2 0.5 lots).
+ The first command sets take profit = 2 times to stop loss.
+ The second command does not set take profit.
+ If the first command touches take profit, then move the stop loss of the second command to breakeven and continue to keep the command going all the way.

WHERE BUY

You just keep the second command going all the way, as long as the price is within two boundaries on BB1 and on the boundary on BB2 or on the middle band.

If the price cuts and closes below the upper band of BB1 (for cautious traders) or the price cuts below the middle band (for high risk traders), close the second command.




CASE SELL

You just keep the second command to go out of the downtrend, as long as the price is within two bounds below BB1 and below BB2 or below the Middle Bound.

If the price cuts and closes above the lower band of BB1 (for cautious traders) or the price cuts and closes above the middle border (for high risk traders), close the second command.
