Feature Request: "Use Closed Candles" option when buying/selling with BBTA

[dric322]

I had an idea for a new feature on the BBTA strategy, for buying and selling.

It could be called something like:
Use Closed Candles
(With on/off toggle).

At the moment, BBTA trades in real-time, in other words it will buy on an open candle if there's a price reversal.

When using BBTA, one thing I realised is, the price can drop under the low BB, then rise again during that same
open candle, which triggers a buy - but then the price could drop again after you bought - which can lead
to ending up in a losing trade, maybe hitting your stop limit, or getting stuck with a bag - when you should be
trading! ;)

The "Use Closed Candles" BBTA feature would behave like this, the rules are logical and simple:

Buy cycle starts when:

• A candle closes under Low BB. When the next candle opens, start the buy cycle. The bot would
  not buy here but just start the cycle and prepare for a price reversal above Low BB.

Buy actually happens when:

• The price reverses and goes above Low BB. This could be on the current open candle, or any future candle.
  (usual BBTA behavior).

It would work the same way (in reverse) for selling, for example:

Sell cycle starts when:

• A candle closes above High BB. When the next candle opens, start the sell cycle. The bot would
  not sell here but just start the cycle and prepare for a price drop under High BB.

Sell actually happens when:

• The price drops and goes under High BB. This could be on the current open candle, or any future candle.
  (usual BBTA behavior).

After scrolling back through the BTC chart (15m period) I can see that using a feature like this when buying
would be useful, over and over again. It would add another layer of safety when buying. This feature can
certainly prevent getting stuck in bad trades.

Buying examples are shown in the image links below.
The last image shows how it would work for selling.

I have used 15m charts in all images below, but the principle works the same on all time frames.

The important thing about this feature would be that it ignores a price reversal on the current open candle.
This would stop a buy being triggered when the price might rise above Low BB, then drop below Low BB on
the same open candle - which is the standard way BBTA behaves when buying. If this feature was used for
selling, there's times when you'd make better gains.

Here's an image to explain how this "Use Closed Candles" feature would work, buying:

Here's an example showing where BBTA bought before a price drop. This was a real buy using BBTA.
This buy would have been prevented if "Use Closed Candles" was in use:

Another buying example:

In the image below, without using this feature, the long green candle could rise above HighBB, then drop below,
then rise above - and do that several times while that same 15m candle is open. Normally, the sale will happen if
the price drops under High BB on the open candle, but notice in the following image that the candle closed
above High BB and none of the following candles dropped below High BB.

I hope this explains why a "Use Closed Candles" feature would sometimes get better gains when selling:

Here's another example where this feature would prevent selling too early:

I could point out these examples... all day long. :P

Gunthy please add this feature for buying and selling.

If it's too complicated to implement a feature like this, then I can understand that it might not be possible
to add this feature - but indicators (and traders in general) work on using closed candles. I think this would
be an amazing feature to have in Gunbot.

This could just be a simple on/off switch, on the "BUY" tab and "SELL" tab of the BBTA strategy.

This closed candles feature is suited to BBTA, but maybe other strategies could benefit from it.

Cheers.
