Invalid volume .... broker does not allow to trade 0.01 lot size for this account? so - download more historical data (is it MT4 or MT5) and try to change lot size to 0.1.

Maybe you have to use
NormalizeDouble() for the lot size

Your code should always check the broker's conditions for allowable volume/lots. Use the "SymbolInfoDouble()" function to obtain the correct details for:

SYMBOL_VOLUME_MIN

Minimal volume for a deal

double

SYMBOL_VOLUME_MAX

Maximal volume for a deal

double

SYMBOL_VOLUME_STEP

Minimal volume change step for deal execution

double

SYMBOL_VOLUME_LIMIT

Maximum allowed aggregate volume of an open position and pending orders in one direction (buy or sell) for the symbol. For example, with the limitation of 5 lots, you can have an open buy position with the volume of 5 lots and place a pending order Sell Limit with the volume of 5 lots. But in this case you cannot place a Buy Limit pending order (since the total volume in one direction will exceed the limitation) or place Sell Limit with the volume more than 5 lots.

You should read and apply Fernando advice.

There are plenty of topics about this issue on the forum.

You don't use NormalizeDouble. You normalise the volume/lots by aligning it with the Volume Step (SYMBOL_VOLUME_STEP) and checking it against the allowable Minimum (SYMBOL_VOLUME_MIN) and Maximum (SYMBOL_VOLUME_MAX) values (see my previous post).
