Is there anyone who can convert a TradingView Indicator to Amibroker AFL? I want to convert this.
This is very helpful in Swing Trading

// - There are drawing/painting issues in pinescript when working across resolutions/timeframes that I simply
// cannot fix here.. I will not be putting any further effort into developing this until such a time when
// workarounds become available.
// NOTE: Re-painting has been observed infrequently with default settings and seems OK up to Alternate
// multiplier of 5.
// Non-repainting mode is available by setting "Delay Open/Close MA" to 1 or more, but the reported
// performance will drop dramatically.
//
// R5.1 Changes by JustUncleL
// - Upgraded to Version 3 Pinescript.
// - Added option to select Trade type (Long, Short, Both or None)
// - Added bar colouring work around patch.
// - Small code changes to improve efficiency.
// - NOTE: To enable non-Repainting mode set "Delay Open/Close MA" to 1 or more.
// 9-Aug-2017
// - Correction on SuperSmooth MA calculation.
//
// R5 Changes by JustUncleL
// - Corrected cross over calculations, sometimes gave false signals.
// - Corrected Alternate Time calculation to allow for Daily,Weekly and Monthly charts.
// - Open Public release.
// R4 Changes By JustUncleL
// - Change the way the Alternate resolution in selected, use a Multiplier of the base Time Frame instead,
// this makes it easy to switch between base time frames.
// - Added TMA and SSMA moving average options. But DEMA is still giving the best results.
// - Using "calc_on_every_tick=false" ensures results between backtesting and real time are similar.
// - Added Option to Disable the coloring of the bars.
// - Updated default settings.
//
// R3 Changes by JustUncleL:
// - Returned a simplified version of the open/close channel, it shows strength of current trend.
// - Added Target Profit Option.
// - Added option to reduce the number of historical bars, overcomes the too many trades limit error.
// - Simplified the strategy code.
// - Removed Trailing Stop option, not required and in my opion does not work well in Trading View,
// it also gives false and unrealistic performance results in backtesting.
//
// R2 Changes:
// - Simplified and cleaned up plotting, now just shows a Moving Average derived from the average of open/close.
// - Tried very hard to alleviate painting issues caused by referencing alternate resolution..
//
// Description:
// - Strategy based around Open-Close Crossovers.
// Setup:
// - I have generally found that setting the strategy resolution to 3-4x that of the chart you are viewing
// tends to yield the best results, regardless of which MA option you may choose (if any) BUT can cause
// a lot of false positives - be aware of this
// - Don't aim for perfection. Just aim to get a reasonably snug fit with the O-C band, with good runs of
// green and red.
// - Option to either use basic open and close series data, or pick your poison with a wide array of MA types.
// - Optional trailing stop for damage mitigation if desired (can be toggled on/off)
// - Positions get taken automagically following a crossover - which is why it's better to set the resolution
// of the script greater than that of your chart, so that the trades get taken sooner rather than later.
// - If you make use of the stops, be sure to take your time tweaking the values. Cutting it too fine
// will cost you profits but keep you safer, while letting them loose could lead to more drawdown than you
// can handle.
// - To enable non-Repainting mode set "Delay Open/Close MA" to 1 or more.
