2 Set of EA, One with Zigzag Buy Sell Indicators, One with Zigzag & One Additional Indicators

Hi I am looking to write a EA based Zigzag buy Sell Indicator, i have a set of the source code.

To enter a buy order, the up arrow will appear, and the exit position will be a dot or down arrow.

And if the down arrow is appear, after closing buy order, a sell order will be placed.

Only when a dot appears, any order will be exit regardless buy or sell.

At any one time, only one order is valid.

Able to enter TP (if any or blank), Order Size, SL.

The second EA will be combination of Zigzag and another customised indicators,

It will be RBR & DBD indicator. (Only Indicator, no source code, i can write the logic on how the zone appear.)

When Down arrow from Zigzag & DBD (Red Color Zone) appear, enter a sell order.

When Up arrow from Zigzag & RBR (Green Color Zone) appear, enter a buy order.

At any one time, only one order is valid.

Able to enter TP (if any or blank), Order Size, SL.

For both EA.
