TTP Gavin's DCA Backtest

Purpose:
The DCA Backtest script was designed to backtest the performance of any indicator using DCA bots.

"Open Deal ASAP" Deal Start Condition:
This script offers "open deal ASAP" deal start condition which will continuously open new deals. IT will wait for the current deal to close before opening a new one.

"Script" Deal Start Condition:
If you select the "Script" deal start condition we provide Bollinger Bands as an example. You can tweak the BB parameters from the indicator settings menu.

"Indicator" Deal Start Condition:
The third option is "Indicator". For this option to work you must have an indicator that plots a unique value that can be recognised as a BUY signal.
We recommend that your indicator plots 1 when it should buy and 0 when there's no signal.
Once you have in the same chart your indicator and your DCA backtest it's time to hook them up. For that follow these steps:
1) select "Indicator" as deal start condition
2) select your indicator from the list as "deal start source"
3) If you are following our recommendation then use 1 as "deal start value" so it can tell the DCA backtest when to open a deal. Make sure that your indicator only plots 0 or 1 so the DCA backtest can distinguish the BUY signal appropriately.

Limitations:
Each time you make changes and save your external indicator while you are backtesting, you will have to hook up the indicator again with the DCA backtest in the settings.
To avoid this, add as many parameters as you need to change in the external indicator so in that way you won't need to save changes to it and therefore will manage to avoid having to hook up the indicator with the DCA backtest.

Versionshinweise:

- All strats now support bearish entries: CCI, MFI, RSI, BB, QFL
- TP % can now be set as low as 0.01

- QFL strategy includes a toggle to require the lower base to be below the upper base to be able to trigger a signal
- Resolves issue of required funds not calculated properly. TV changed a method today which broke our script. Thanks to Gavin for finding a fix to this issue so quick! it took us a few minutes but it was crazy!
- Resolves an issue caused.by having too many SOs

Versionshinweise:

- added new stop loss percentage parameter to DCA settings

Versionshinweise:

- Added TradingView Technical Indicator deal start conditions. 3 timeframes
- Ultimate oscillator bug fix: first two were not working properly

Versionshinweise:

QFL deal start condition now allows multiple consecutive deals. Before, if there were 20 candles signalling BUY, only the first would trigger a buy, now all of them would.

Versionshinweise:

There was a problem that even while using "open deal ASAP" the backtest wasn't opening an deal right after closing the previous deal. There was a single candle that the strategy was idle. This change seems to resolve it. I will keep an eye in case the fix had any side effect, in which case I might have to revert it and find an alternative solution.

Versionshinweise:

Solves an issue when the DCA was buying at negative prices even when the SOs max deviation shouldn't hit negative prices.
I tested this solution on IFTRSI external indicator and managed to stop getting the error, if the same error occurs please report it on our discord server DCA-backtest channel.

Versionshinweise:

1) We created a new deal start type: External signal + 3C simulator combined.

This should be quite useful as 3C actually DOES support mixing their built-in indicators with an API signal, which is exactly what this mode represents.

The DCA bot will only open the trade if there's a BUG signal and all the 3C simulator conditions enabled are valid at the same time.

An example of a cool use could be to only take BUYs from the external signal when TV is BUY on the daily and hourly and RSI daily is below 80.

If you enable this mode you have to connect a backtestable compatible signal (for example one that only prints ones and twos, for buys and sells) and you MUST enable at least one of the 3C simulator deal start conditions. If you don't enable any, the simulator won't open any deal. Remember this behaves as an AND operator, all enabled conditions + the BUY signal itself must be true to open a deal.

The intention is to mimic how exactly how 3C behaves when using this approach.

2) Now the results table renders in green when there's a deal open in profit. If the deal is open and it's at a loss it still renders it in red.

Versionshinweise:

open trades appear in green when there's an open deal in profit

Versionshinweise:

I think it's time to give some love to the stop loss:
- Now the backtests calculates the SL% relative to the base order just like 3C does. Before we were using relative to the average position price.
- If you use SL we plot the SL level in grey. Before it was not possible to know where is the SL located in the chart.

Versionshinweise:

- added Bollinger bands % indicator

Versionshinweise:

- Improved performance, reduce unnecessary use of security function
- Added support for RSI14, MACD, PSAR

Versionshinweise:

New deal start conditions supported:
- SMA
- Heikin Ashi

Versionshinweise:

Added total deal count to show even if deal is open.

Two issues resolved:
1) Total days in results table shows duration from Start Date until Current Time. If End Date is set on a historic date it doesn't reflect in Total days.
2) When current deal is in profit but not closed = show green background in table.

Versionshinweise:

Solves issue causing wrong "days in deal" calculation when the selected date was in the future.

Versionshinweise:

- Support for max and min price: it will skip a deal if the price is not above the specified min or below the max). The value zero disables min/max.
- Support for timeout. After the specified timeout in bars the deal will close. Use zero to disable this option.
- Fixed issue where summary was shown in red in the results even though it did close all deals in profit.

Versionshinweise:

- Volume filter accuracy improved: has been re engineered to match better the one used by 3commas
- Timeout bug: solve issue with the timeout settings that was counting from each individual DSC event rather than from the time the deal actually opens.

Versionshinweise:

What's been done:
fee's added as a DCA setting (DCA calculation bug, should be synced with commission)
added Plot deal stop condition

Updated results table:
Title row: Updated name + color to top row and moved token to right, more compact
Left column: aligned text right, renamed names
Rearranged order of info to make more sense (to me at least...)
Max SO count fixed for edge case (display only)
condensed large values: if > 0 skip decimals, if < 0 use decimals
Moved deals completed to new row (from Status)
Combined related values into 1 row instead of 2
If short mode: shows Initial USD required to run (otherwise hidden)
If no deal yet: show "no deals yet" in status row instead of "all deals closed (0)"
if no deal yet: show "-" on relevant values instead of "0"
if no deal yet: background color grey instead of red

Versionshinweise:

fix for broken min, max price limits and cooldown.

Example code of an external ORC signal

The ORC script below will only start the bot when RSI is above 50.
```
//@version=5
indicator("RSI ORC", overlay=false)
rsi = ta.rsi(close, 14)
plot(rsi > 50 ? 3 :4, "RSI ORC")
```
