I have published that script not like oscillator, which in fact it is, because tradingview doesn't support dual plots in overlay=true and overlay=false. So I have decided that to show filter is better idea. Yes, it decrease potential profit on long term, but for me personally, it is much better to understand the direction of the market movement and take potential trades more seriously. Also about this script: in general based on RSI and works pretty nice on 1H timeframe. Yes, theoretically it can work on both 4H and 1D timeframes, but for this you need to change the settings that are not displayed in the inputs (I did not add them, due to the fact that they can be confusing, because I decided to add a filter). And about filter - it is one of the variations of the SuperTrend. According to House Rules, I cannot insert links here, but only if you are interested in trying this work in auto trading, you can follow the link (located even lower) and find there an algorithm with the same name.
Notes de version
⋅
The algorithm was modified and replaced on 4H timeframe due to continuous bear market and fake trades. Also the new exit point added in code.
