Few questions about entry and exit signals

[Krzysiek191]

Hi!

I am trying to use imported indicators but I am having problems with setting the entry and exit signals. For an example: some indicators are just oscillators. I imported Chaikin Money Flow Indicator from Python ta CMF = vbt.ta('ChaikinMoneyFlowIndicator').run(high, low, close, volume, 20).chaikin_money_flow and want to set the entry signal for when it crosses above 0 and the exit signal for when it crosses below 0.2. How can I do that? Plain CMF>0 and CMF<0.2 does not do the job. With build in indicators like RSI or MA it's rsi_crossed_above or ma_crossed_above and ...below.
But how can I do it with imported indicators?

Also:

How can I set signal which are more complicated? I mean, not one but two or even more conditions must be met to execute an entry or exit order. For example: MA 14 crosses above MA 50 and at the same time RSI is at least 50, and CMF 0.1 or more.
What would the code for an entry signal like this suppose to be?

@Krzysiek191 for each input and output there is _above and _below method (chaikin_money_flow_above, etc.). Other than this, you need to elaborate why exactly CMF>0 and CMF<0.2 don't do the job.

[Krzysiek191]

cmf = vbt.ta('ChaikinMoneyFlowIndicator').run(high, low, close, volume, 20).chaikin_money_flow
entries = cmf.chaikin_money_flow_crossed_above(0)
exits = cmf.chaikin_money_flow_crossed_below(0.2)

Returns an eror "AttributeError: 'Series' object has no attribute 'chaikin_money_flow_crossed_above'"

With cmf>0 and cmf<0.2, the problem is with the exit signal. It makes my entries unpossible because everything below 0.2 is a sell signal so no entries below that can happen and I want to enter at above 0...

Remove .chaikin_money_flow from the first line.

Thanks! I was following examples: https://vectorbt.dev/getting-started/features/#indicators
