I just did a quick manual backtest GBPJPY from january 19 2017 to march 19 2017 40,15,10,20,-20,-20,-3,30,38,-20,27,-20,20,-20,-20,20,30,-20,-20,19,46,-20,-20,-20,34,-20,17,16,-20,28,32,22,30,30,26,27,-20,-5,-20,12,33,-20,28,36 280 pips total 26 wins 18 losses.
great! notice how that out of the tiny sample of 44 trades, more than half are winners and that out of those wins, 17 are greater than 20 pips, meaning that the R:R is greater than 1...

I'm trying to help improve your Bollinger Band strategy when I read this: "This adaptive version applies the concept described by John Ehlers in the book Rocket Science for traders, for making standard indicators adaptive . The indicator uses the homodyne descriminator to compute the dominant cycle. To apply the homodyne descriminator, real and imaginary parts have to be calculated from the Inphase and Quadrature components. (Inphase and Quadrature components are deduced using the Hilbert transform. To learn more about this, read the article on...

trading doesn't need to be this complex

now what would be really interesting is to examine the losing trades and see how many of them were in profit from entry point before stopping out and by how much.

{quote} thanks hibra68, what I've found is that when a BB squeeze is on and price first breaks out, it breaks hard in the opposite direction of the imminent trend then snaps back. I've always used 14 as my default MA but anyone is welcome to experiemnt with whatever BB Ma setting they wish.
I'm very interested in your findings: "I've found is that when a BB squeeze is on and price first breaks out, it breaks hard in the opposite direction of the imminent trend then snaps back."
-- I'm trying to understand it. In your findings price usually snaps back many pips away from breakout (far above or below)? Then you repeated "first breakout, it breaks hard in the opposite direction". I'm wondering, could you explain what you mean? I was thinking you found out that 1. first price breaks out above (5-10 pips) and then price returns and breaks out below the bollinger band at the other side (50-100 pips). Could you explain if this is what you mean?

ok so I've been playing aorund with double bollinger bands and I have another trading idea. I've looked at this on GJ and GU. still using the double bollingers with standard deviation of 1 and 2 and MA of 14, look at the 15 minute timeframe. When price closes below the lower BB (the navy one), buy at open of next bar with a TP of 5 pips and a SL of 10 pips. If stopped out, immediately open a trade again in the opposite direction (go short). Reverse for longs.

The close must not be touching the BB, it must clearly close beyond it.

Here's an example of a stop and reverse scenario. Bar 1 closes beyond the lower BB. Enter a buy at open of Bar 2. Tp 5 pips, SL 10pips. Price never went up and trade gets stopped out. Immediately enter a sell with TP 5pips, SL 10. The theory behind this is that it aims to capture the price movement when a trend is in place following a BB squeeze. If this gets stopped out we wait for the next trade ( a close beyond one of the navy BBs.

Dear HarryPlopper,
Great idea, have you counted the stats based on 30-100 trades? Does it remain profitable after so many trades? I will test this myself this weekend also (if you do not mind) and see if I can add anything to help

Best Regards,
Tzamo

The original system is profitable, 44 trades over 3 month period with 280 pips in profit. 26 winners 18 losers. Average rr is better than 1:1
Maybe someone should make EA for it than improve on thst.

I thought I'd share some preliminary findings. Have just been doing a manual backtest for the 1hr system as posted in post 1. However, I've looked at additional profit targets as well as the SD1. My broker is Pepperstone. Starting from yesterday (28th June) I've looked back at all trades to the 1st of May.

34 trades.
9 trades hit the SL. Out of these 9 trades, 3 of them were in profit at least 20pips before stopping out.
6 of the winners reached the red SD1.
4 of the winners reached the central MA.
4 of the winners reached the opposite SD1.
11 of the winners reached the opposite SD2.

Therefore, 25 of the 34 trades hit at least the SD1 band. I did not record the pips gained at the SD1 band for the winners that reached the MA, opposite SD1 and opposite SD2.

For all winners, I recorded down the pips gained for each trade.

Of the 11 winners reaching the opposite SD2, the total pips was 880. The average win was 80.5 or 4xSL.

Already I am thinking that an EA could be coded to move the SL to breakeven once the first SD1 has been reached or simply a set 20 pips, with a TP of the opposite SD2 or to take half the trade as profit at SD1 and the other half off at the opposite SD2 or to exit the trade when the SD1 has been hit (giving the highest probability of success) or aiming for the opposite SD2 (which may provide the best R:R overall)

Is this based on the 5 pip TP and 10 pip SL?

Quick backtest over the past week on GJ. Decided against the stop and reverse rule, just a set TP of 5 and SL of 10..

29 trades, 23 winners, 6 losses

Have you considered that the BBs didn't have the same placement in real time that they have when you do a visual back test?
Looking back, you see the BBs as they looked when the bar closed. In real time you see the BBs as they look when the bar is forming.

hi billbss, nope hadn't considered that. would you suggest forward testing an EA for a few months instead?
