Design and implement three default parametrized models for liquidity distribution

[Desrever Nu]

Design and model three basic models for liquidity distribution :

• Implement a simple linear model
• Implement a simple logarithmic model
• Implement a simple exponential model
• Models should allow for sell-side and buy-side liquidity separation
• Models should allow for parametrisation
• Make the liquidity model abstract class LiquidityDistributionModel

Add a method that given the model, returns a set of orders based on available liquidity and other params, similar to

public ArrayList<OrderToPlace> getOrdersToPlace(String type, Amount fundsAvailable, double pegPrice, CurrencyPair pair, double txFee) ;

Also remind to assign proper default values at config level ! NuBotOptionsDefault.java

Set an hard cap on the maximum number of orders per side (12)

All available balance should be put on tier2. which is now separately managed from tier1(walls)

like this

default model , use ,

  public static ModelParameters getStandardParams(String type) {

        double wallHeight = 500;
        double wallInterval = 0.008;
        double wallMaxWidth = 0.4;

        LiquidityCurve curve = new LiquidityCurveExp(LiquidityCurve.STEEPNESS_LOW);

        double offset;
        if (type.equals(Constant.SELL)) {
            offset = 0.004;
        } else {
            offset = 0.007;
        }

        return new ModelParameters(offset, wallHeight, wallMaxWidth, wallInterval, curve);

    }
