This is the Stochastic Adaptive Lookback Speed indicator for MT4 which was kindly created and also upgraded by Mladen to include Multi-timeframe + Interpolation.

As a note, this particular Stochastic is more suited to scalping as it reacts to price a bit faster than the standard Stochastic Oscillator.
For swing trading, this can still be used, but you'll want to adjust the settings to 14, 3, 3. For scalping, the default 5, 3, 3 settings are ideal.
